1. GaN, AlGaN, GaNAs and Related Heterostructures Grown by Molecular Beam Epitaxy
Abstract : This work deals with growth and characterization of III-nitrides and related heterostructures as well as GaNAs alloys grown by plasma assisted molecular beam epitaxy (MBE). The III-nitrides belong to the wide bandgap semiconductors due to their large energy bandgap spanning from 1.9 to 6.2 eV. READ MORE

2. Linear and Nonlinear Transport in Quantum Nanostructures
Abstract : In this thesis, electron transport in mesoscopic semiconductor nanostructures, in particular so-called electron billiards or quantum dots, is studied. The thesis can be divided into two areas: the linear response regime of transport, and the nonlinear response regime of transport. READ MORE
