Nano and Optoelectronics Research Group

Research activities of our group are on electrical, optical, and structural characterization and magnetotransport properties of novel semiconductor alloys and devices based on conventional III-V alloys and highly mismatched alloys (HMAs) as well as synthesize/fabrication and imaging of nanostructures. The research laboratories comprise of three laboratories:

1. Clean room and Micro/Nano-fabrication facility - Advanced Lithographic Techniques Laboratory (ALTL)

Clean room and micro/nano-sized fabrication facility has been established in 2013 with an infrastructure project supported by Development Ministry of Turkish Republic. There are 3 sections in the 100 m2 clean room area; 10, 100 and 1000 classes. These lasers are described by the particle number bigger than 0.5 micron in per cubic feet. Micro/nano-sized fabrication optoelectronic and electronic devices are fabricated using photolithography and dry etching techniques (Focused ion beam and electron beam lithography techniques). SEM, EDS and AFM are also available for structural characterization. For details, please visit Research Facilities section

2. Nano- and Optoelectronic Research Laboratory :

In this laboratory, experimental facilities exist to investigate electrical, optical and magnetotransport properties of novel semiconductors and devices at temperatures between 1.3K and 300K. The experimental set-ups include magnetotransport, electrical transport, optical characterization (Photoconductivity, photovoltage, reflectivity), I-V measurements, modulation spectroscopy, and photo-induced transient spectroscopy (PITS).

3. High Magnetic Field and Low Temperature Laboratory :

Magnetotransport measurements are carried out using 7T or 18T superconductive magnets from 10mK to 300K. Close Detail


We congratulate them on their successes:

That's the First National Patent of Istanbul University Physics Department and Nano and Optoelectronics Research Group. Prof. Dr. A. Erol, Prof. Dr. N. Balkan and Res. Assit. F. Sarcan got the first national patent about " Resonance Cavity Enhanced Photodedector with Internal Gain" by Turkish Patent and Trademark Office.

Two Research Projects Submitted :

Two research projects submitted by our Research Group Members, Ömer Dönmez and Barış Kınacı, have been approved by The Scientific and Technological Research Council of Turkey (TÜBİTAK).

First Optoelectronic Device:

First optoelectronic device, resonance cavity enhanced photodetector, is fabricated using clean room facilities (Photolithography) of Advanced Lithophrapy Techniques Laboratory. The device is designed and fabricated for 1.3um window of the optical fiber communication systems as an outcome of a TUBITAK-funded project. We commemorate Prof. Naci Balkan who was a researcher and mentor of this project.
