| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Recently one more design freedom of change the barriers height in THz QCLs is expected to improve device performance and combine different kind of advantage design simultaneously. Our aim is to achieve the thermoelectric cooling temperature operation THz QCLs combine with high Al composition structure with variable well-barrier height design. Here we present a primary experiment results by first arrange the recently recorded 3-wells resonant tunneling structure design with the reducing of the emission barrier height and adding an external thin barrier near the extraction barrier in the extraction/injection well. This modulation barrier THz QCLs succeeds lasing at 3.7 THz with the maximum operation temperature up to 112 K. | |
