In the case of weak magnetic fields when the cyclotron frequency is smaller than LO-phonon frequency (omega(c) omega(LO)), the cyclotron masses m(c+)*, and m(c-)* decreases and increases with increasing temperature, respectively. 关键词: NANOSTRUCTURES; SEMICONDUCTORS; ELECTRON-PHONON INTERACTIONS; SEMICONDUCTOR MICROCRYSTALLITES; CYCLOTRON-RESONANCE; PHONON COUPLINGS; SIZE DEPENDENCE; ELECTRON; PARTICLES; POLARON; STATES; ENERGY SIZE DEPENDENCE; ELECTRON; PARTICLES; POLARON; STATES; ENERGY
