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.
Institute of High Pressure Physics and Gdańsk University of Technology, Faculty of Applied Physics and Mathematics, represented by professor Wojciech Sadowski, start the partnership in TEAM-TECH project.
16.07.2018 Congratulation to Mateusz Hajdel on an excellent defense of his MSc thesis (with honors). Mateusz Hajdel is a laureate of the Fundation for Polish Science scholarship and a team member of TEAM-TECH project.

Video (only Polish language version) recorded in 2014 - “Patent na Patent”:
From this short video you can learn about Grzegorz Muzioł PhD thesis (4:10). He explains the role of InGaN laser diode waveguide design on the optical mode leakage to GaN substrate (5:08). You can hear Prof. Czesław Skierbiszewski tellinng about the properties and applications of gallium nitride (3:25), and Prof. Piotr Perlin (TopGaN CTO) stressing the importance of innovative research for polish hi-tech business (8:34).
