Abstract
We have studied the effect of an external magnetic field on electron-a coustic phonon scattering in rectangular quantum wires taking into acc ount both electron and phonon confinement. A magnetic field has two ma jor effects: (i) it dramatically quenches (by several orders of magnit ude) intrasubband scattering due to acoustic phonons in hybrid ''width '' and ''thickness'' modes, and (ii) it increases electron interaction with evanescent hybrid surface modes that peak at the wire edges. A s imple intuitive picture to elucidate the origin of these effects is pr esented. [S0163-1829(98)08908-5].
