Abstract

We demonstrate room temperature intersubband transitions in the THz range using continuously-graded Alx Ga1-xAs parabolic quantum wells. Below 100K, the linewidth of the transition reaches a record-low value of 5.7% of the central frequency.
连续梯度AlxGa1-xAs抛物量子阱的室温太赫兹子带间跃迁
我们使用连续梯度的Alx Ga1-xAs抛物量子阱演示了室温下太赫兹范围内的子带间跃迁。在100K以下,过渡的线宽达到创纪录的低值,为中心频率的5.7%。
