Abstract
We have employed a novel Monte Carlo technique for the self‐consistent simulation of electron transport and noise in GaAs quantum wires at low temperatures. The electron noise at low electric fields is completely controlled by acoustic phonon scattering. It is demonstrated that the efficiency of acoustic phonon scattering decreases as the electric field increases. As the result electron mobility and noise increase as the field initially increases. With further increase in electric field the role of optical phonon scattering increases and the electron noise starts decreasing and finally collapses at the streaming frequency.
