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.
09.09.2019 Julia Sławińska and Natalia Fiuczek defended Master Thesis with honours. They carried out the research in Institute of High Pressure Physics PAS within Foundation for Polish Science projects: "Tunnel junction and its applications for GaN based optoelectronics" leaded by prof. Czesław Skierbiszewski and "Development of high quality InAlN – the road to strain-free nitride lasers" leaded by dr inż. Marta Sawicka. Congratulations!
