Photoluminescence of CdTe crystals grown by physical-vapor transport
High-quality CdTe crystals with resistivities higher than 108 Ω cm were grown by the physical-vapor transport (PVT) technique. Indium, aluminum, and the transition-metal scandium were introduced at the nominal le...

Search for Spin Filtering by Electron Tunneling Through Ferromagnetic EuS Barriers in PbS
Perpendicular transport through single- and double-barrier eterostructures made up of ferromagnetic EuS layers embedded into a PbS matrix was investigated. Both resonant tunneling and probably spin filtering t...
