SEMINAR
Growth of nanostructures by molecular beam epitaxy
Otto Mønsted Visiting Professor George Cirlin
St. Petersburg Academic University
An overview of the growth activities at Academic University will be given. I will start with the facilities description which we have in the lab and show which particular materials may be grown. Mostly, we are concentrated in growing classical A-III B-V materials for optoelectronic devices, like lasers emitting at different wavelengths, from visible to THz. Another direction of our activity is the growth of nitrogen-based materials, like GaN, AlN, InGaN, etc. Main attention will be paid for the nanowire (NW) growth of different materials. We will discuss the growth mechanisms responsible for the formation of the NWs via a bottom-up approach, the growth of NWs on silicon, and, finally, the growth of heterostructured NWs. Structural and optical properties of the NWs will be presented.
