Summary of Valdas Jokubavicius's activities

Research

My research addresses two main topics:

  • Epitaxial growth of silicon carbide (SiC)
    This topic covers growth and characterization of nitrogen and boron doped  6H-SiC and 3C-SiC layers on low off-axis hexagonal SiC substrates. The layers are grown using sublimation epitaxy which is a modification of Physical Vapor Transport (PVT) technique.

  • Thermal etching of SiC surfaces
    This topic involves thermal etching of SiC process development and optimization in order to obtain high quality surfaces for subsequent epitaxial growth of SiC or graphene. The etching is done using custom-design thermal etching reactor.
