On effective electron mass of silicon field structures at low electron densities

Determination of electron effective mass and electron affinity in HfO2 using MOS and MOSFET structures

We present a combined electrical and modeling study to determine the tunneling electron effective mass and electron affinity for HfO2. Experimental capacitance-voltage (C-V) and current-voltage (I-V) characteristics are presented for HfO2 films deposited on Si(100) substrates by atomic layer deposition (ALD) and by electron beam evaporation (e-beam), with equivalent oxide thicknesses in the ran...

Mass-Shell Behavior of Electron Propagator at Low Temperature

In high temperature gauge theories the fermion propagator is quite di erent than at zero temperature [1] and calculations require the Braaten-Pisarski resummation of hard thermal loops [2{4]. One of the important quantities to be calculated is the imaginary part of the fermion selfenergy, or damping rate, which has been computed in various circumstances. In QCD the massless gluons are so change...
