Semiconductor Based Optoelectronic devices
New Semiconductor Nanostructures
Photonic Crystals
The PEG has significant efforts in the area of modeling of semiconductor based optoelectronics devices. Research works in PEG cover wide range of optoelectronic devices such as Photodetectors, Light emission diodes, solar cells, transistors, modulators. In this regards, PEG has focused on the study of optical and electronic properties of III-nitride heterostructures and semiconductor nanostructures like QDs, QWs for high performance electronics and optoelectronics. More recently PEG interested in hybrid structure based on new materials like graphene and other semiconductors. Experiments are of particular important in PEG.

Besides, new semiconductor nanostructures, more importantly, 2D type, gained renewed interests due to unique optical and electronic properties and potential applications. They are one of the most active fields of research in Physics, Chemistry, Material and nano science. Very interesting phenomena have been emerged 2D atomic crystals. Graphene and related 2D materials such as MoS2, BN, WS2, Silicene, Phosphorene,…pave the ways towards new optoelectronics device applications like resonant diodes, transistors, photovoltaic sensors. The study of these new emerged nanostructures the view point of optical properties and modeling of their devices is new interesting in PEG. Group is providing the stage of experimental works in this field

In addition to aforementioned interests, due to especial importance of photonic systems in the field of optoelectronic devices, PEG has focused on photonic crystals. Photonic crystals are usually viewed as an optical analog of semiconductors that modify the properties of light similarly to a microscopic atomic lattice that creates a semiconductor band-gap for electrons. It is therefore believed that by replacing relatively slow electrons with photons as the carriers of information, the speed and band-width of advanced communication systems will be dramatically increased, thus revolutionizing the telecommunication industry.
The activities of the PEG focuses on the photonic band gap engineering, tunable photonic crystals, metallic photonic crystals, surface states, photonic crystal waveguides, photonic crystal fibers, nonlinear photonic crystals for photonics applications.
