摘要 | Cyclotron resonance of magnetopolarons in a parabolic quantum dot with weak magnetic field normal to the plane of the quantum dot is investigated theoretically. It is shown that for weak magnetic field (omega(c) much less than omega(LO)), the cyclotron mass in a parabolic quantum dot is split into two cyclotron masses (m+* and m-*). One (m+*) is larger than the bare band mass for large quantum dots but is lower than the bare band mass for small quantum dots, and with decreasing the effective confinement length of the quantum dot, the negative mass renormalization for the small quantum dots is important. The other (m-*) is greater than the bare band mass and might be a measurable effect for the small quantum dots. |
