Electron-LO phonon and electron-electron transition rates are calculated for a three-level triple quantum well system to be employed as a laser operating in the far-infrared (30-300 Β΅m) or terahertz (1-10 THz) region. The population ratio is determined from the ratio of the carrier lifetimes in leve
