Electrons and holes in Si quantum well: a room-temperature transport and drag resistance study
M. Prunnila, S. J. Laakso, J. M. Kivioja +1
We investigate carrier transport in a single 22 nm-thick double-gated Si quantum well device, which has independent contacts to electrons and holes. Conductance, Hall density and H…

Energy Transport between Hole Gas and Crystal Lattice in Diluted Magnetic Semiconductor
J. M. Kivioja, M. Prunnila, S. Novikov +2
The temperature dependent energy transfer rate between charge carriers and lattice has been experimentally investigated in ferromagnetic semiconductors. Studied 100 nm thick low-te…

Electron-Acoustic Phonon Energy Loss Rate in Multi-Component Electron Systems with Symmetric and Asymmetric Coupling Constants
Mika Prunnila
We consider electron-phonon (\textit{e-ph}) energy loss rate in 3D and 2D multi-component electron systems in semiconductors. We allow general asymmetry in the \textit{e-ph} coupli…
