Abstract
Dissipative electron transport in a free-standing semiconductor wire is considered. Dependences of the drift velocity and electron temperature on the applied electric field are found. It is shown that the effective cooling of electrons which takes place at a certain region of the lattice temperature gives rise to an instability of the steady state, and to negative differential resistivity.
