Bilkent prides on well-established research infrastructure along with UNAM facilities and ranks among the top in terms of research outputs in science/engineering in Turkey.

The Devices and Sensors Research Group is also very active in synergic entrepreneurship activities in Turkey, Europe, the US and Asia, based on high-technology prototypes the Group have developed and in taking new ideas from the lab to the market. Professor Demir is director of LUMINOUS! Centre of Excellence for Semiconductor Lighting and Displays in Nanyang Technological University, in Singapore. Also, Professor Demir is a co-founder and a partner of several successful startup companies. Based on their joint research work and intellectual property, he first co-founded a nanotechnology based company, called InnovNano, which was then successfully turned into a joint venture, called InnovCoat.

Photonic Crystals team

CSIC logo

The ICMM institute, acronym for the Spanish Madrid Institute of Materials Science, belongs to the Spanish Research Council (CSIC) and its main objective is to create new fundamental and applied knowledge in materials of high technological impact, their processing and their transfer to the productive sectors at local, national and European scales (the true value of materials is in their use), the training of new professionals, and the dissemination of the scientific knowledge. Belonging to Photonic Materials, one of the seven research lines ICMM is divided, the Photonic Crystals Group comprises 2 permanent Researchers, 2 Postdocs and 3 PhD students working in the fabrication and optical studies of photonic crystals and photonic glasses by self-assembly. Headed by Prof. Cefe López and with a background in optical properties of semiconductors, the group has accumulated over twenty years’ experience in the field and renown at world level.

Coordination team:

KTH - Kungl Tekniska Hogskolan

Division of Semicondutor Materials

KTH logoThe participating groups has extensive expertise on Photonic Integration, III-V nano-structures and nano-structured materials, covering physics, technology and applications.

Research group of S. Anand: The group is a pioneer in deep-etching of photonic crystals in InP-based structures and has demonstrated several devices or device-concepts such as lasers, filters, and negative-refraction. The group has also made significant contributions on the understanding of the physical mechanisms in nanofabrication of photonic crystals and its implication on electrical conduction. Nanostructuring (random) on Si, III-Vs using a combination of colloidal lithography and dry etching has also been developed. Self-organized formation of nano-pilars in InP-based materials has been developed. Such pillars can also be composed of multiple layers composing InP, GaInAsP, InGaAs – thus covering a wide band-gap range. The methodology and application of Atomic force microscopy based electrical characterization techniques have been established for 2D mapping of the electrical properties of materials and devices, including low dimensional structures containing QWs/Q-dots, with nanoscale spatial resolution.

Research group of S.Lourdudoss: The group has pioneered epitaxial solutions such as selective area growth, epitaxial lateral overgrowth and heteroepitaxy. Specific expertise include selective area growth of III-Vs on planar and non-planar substrates for discrete and integrated components; heteroepitaxy for Si-photonics and for large size III-V layers on Si for applications such as solar cells. The group specializes on high speed devices for telecom applications, novel solutions for optical interconnects, and high temperature quantum cascade lasers for sensing applications.

TUD · Technische Universität Dresden

TUD logoThe TUD group has a long lasting expertise in modeling, synthesis, characterisation, functionalisation and assembling of colloidal semiconductor and metal nanocrystals (NCs). Semiconductor nanocrystals also known as quantum dots have attracted considerable attention because of their appealing optical properties such as strong, narrow, and tuneable (quantum confinement) photoluminescence with quantum yields in the region of 30-95% and full-width-half-maximums (FWHM) of 20-50 nm. Amongst other attractive properties of NCs are their high extinction coefficients (at least an order of magnitude higher than organic dyes), stability (common for inorganic materials), and variable surface functionalities which determine their processability. Metal nanocrystals possess pronounced surface plasmon resonances which are size-dependent and remarkably sensitive to the chemical composition of the nanocrystal surface. The combination of all these properties makes both metal and semiconductor NCs very promising for a variety of active applications in nanophotonics and optoelectronics, including LEDs, solar cells, lasing, optical sensors, colour conversion layers, bioimaging, etc. Assembly approaches are considered as important tools for nanotechnology allowing a predictable and reproducible handling and addressing of nanoobjects. The TUD group is an expert in the layer-by-layer electrostatic assembly, solvent-controlled precipitation, covalent linking, gelation, 1D assembling by oriented attachment, nanoparticle self-assembly, fabrication of robust all-inorganic composites, etc. These methods being applied to the variety of available nanocrystals allow the fabrication of functional composites possessing desirable properties as demanded by the particular nanophotonic and optoelectronic application.

UPC · Universitat Politècnica de Catalunya

Micro and Nanotechnologies

logo UPCThe group brings to the network the expertise in PV solar cell fabrication, technology and measurements.

We have developed state of the art technology for high efficiency silicon solar cell fabrication. In particular and related to the topic of the network (Nanophotonics for Energy efficiency) we fabricate IBC solar cells  (Interdigitated Back Contact) with efficiencies over 22% and 9 cm2  (independently measured). This cell structure, leaving the front surface moderately doped and free of contacts is an ideal benchmark for exploring new nanophotonic approaches  improving the absorption/volume ratio and hence the efficiency.

In this context we have explored the use of colloidal photonic crystals and their compatibility with Silicon solar cell technology. These colloidal photonic crystals can be deposited on large surfaces through a new technology developed by our group and used either directly or as a template for reverse opal formation.  We have also explored silicon microspheres as light traps and other high refraction index nanostructures in particular we have recently obtained the world record efficiency in so-called black Silicon solar cells.

Other cutting edge activities relates to the fabrication of selective thermal emitters for thermophotovoltaic applications and the invention of a procedure called "Silicon Millefeuille" allowing to obtain multiple ultra-thin crystalline Silicon layers from a single Silicon wafer.

Finally, and closer to mainstream industrial application, we work also on HIT solar cells, surface passivation layers research, and laser applications to solar cell technology.

Hybrid Optoelectronics

US logoThe Southampton node brings to the Network its expertise in the optical spectroscopy of semiconductor nanostructures and a variety of fabrication methods of novel nanoscale structures. The group possesses large experimental infra-structure with four fully equipped laboratories for optical spectroscopy and characterisation of semiconductor devices. Relevant to the proposal, these include high spatial/spectral resolution set-ups for low temperature spectroscopy (including magneto-spectroscopy), equipped with both continuous wave picosecond and femtosecond tuneable wavelength lasers, and ultra-sensitive detectors of both optical and electrical signals including a streak camera with 2ps resolution. In addition, the group strongly benefits from the recent investment of the University of Southampton, Merck and the Research Council of UK in extended nano-prototyping cleanroom facilities worth more than £30m.
