The maximum-anisotropy approximation, introduced by Baraff for the solution of the Boltzmann equation in semiconductor problems, is used here analogously for discussing the electron motion in a ionized gas. An expression for the drift velocity of electrons is derived under simplifying assumptions on ...

Drift velocity is the average velocity attained by charged particles in a material due to an electric field. The drift velocity of an electron for a unit electric field is called the mobility of the electron.

velocity W, the expression for w(c0) must be averaged over the initial distribution function f0(c0). The initial velocity distribution, not being affected by the electric field, is isotropic when the differential collision cross section is isotropic. Therefore, the resulting integral equation for ...

With the induced charges and the time between the two signals, which corresponds to the drift time for the applied electric field, the electron drift lifetime can be inferred by solving numerically the equation: QAQC=t1t3e−(t1+t2+t3)/τ(et3/τ−1)(e−t1/τ−1) . (3) Here...
This is the well-known equation for current gain cutoff frequency modified by the added term called modulation efficiency (ME) of the device: (5)ME=∂QSVM∂QSVM+QGCA+QSL. This concept has been used successfully (Foisy et al., 1988) to explain the higher and broader peak of fT as ...
The electron swarm behaviour in monosilane is studied for E/p0 from 0.2 to 300 V cm-1 Torr-1 by a Boltzmann equation method. A set of electron collision cross sections is determined by fitting the calculated values of the drift velocity, characteristic energy and effective ionisation coefficient...
