Institute of High Pressure Physics PAS


About us

MBE research group is a part of the Institute of High Pressure Physics Polish Academy of Sciences (IHPP PAS) "Unipress".

We focus on the development of blue and green light-emitting diodes (LEDs) and laser diodes (LDs) using plasma-assisted molecular beam epitaxy (PAMBE). We carry out the research on long-wavelength light emitters: implement improvements in structure design and optimize optical and electrical parameters of gallium nitride (GaN) based devices. We investigate crystal growth mechanisms on GaN surfaces of various polarity and crystallographic orientation. We fabricate and study nitride heterostructures with tunnel junction. We also study vertical heterojunction transistors n-p-n (GaN/InGaN/GaN) fabricated on GaN substrates using MBE.
