Barış Manço, 1983.


Collaboration Opportunities

I am open to all scientific collaborations. Please do not hesitate to ask, what we can do. I am mostly interested in Electron and magnetotransport properties of III-V group semiconductor materials, Transport properties of low-dimensional systems as Quantum dots (0D), Quantum wires (1D), Quantum wells (2D), transport, strain, quantum parameters of 2 dimensional electron gas (2DEG) and 2 dimensional hole gas (2DHG) of AlGaN/GaN and AlInN/GaN HEMT structures, hot-electron transport phenomena.

Now, I am working on...
  • Investigation of the effects of growth temperature of AlInN layer on transport properties of AlInN/(AlN)/GaN/AlN systems.
  • Electrical and structrucal investigation of AlGaN/GaN based HEMTs with InGaN back-barrier layer.
  • Numerical investigation of AlInN/(AlN)/GaN/AlN systems with low-In barriers.
slow or waited works.. :)
  • Hot-electron transport properties of AlGaN/(AlN)/GaN/AlN systems.
  • 1D-2D Schrödinger-Poisson Calculations on Normally-Off AlGaN/GaN HEMTs with Thin InGaN Cap Layer
