Abstract
- Vertical transport in short-period InAs/AlSb superlattices with type-II heterojunctions is studied at room temperature. It is found that negative differential conductivity appears in the miniband-conduction mode upon the overlapping of quantum-confined states in a periodic system of quantum wells. In the nonresonant-tunneling mode, equidistant peaks appear on the current-voltage characteristic of these superlattices. These peaks are attributed to the influence of the optical cavity on optical electron transitions in quantum wells (Purcell effect).
