| 摘要 |
A two-colour radiation detector (2) comprises a mesa-type multi-layered mercury-cadmium-telluride detector structure monolithically integrated on a substrate (6). The detector (2) is responsive to two discrete wavelength ranges separated by a wavelength range to which the detector (2) is not responsive. The detector (2) further comprises two contact points (12) deposited on the layer disposed furthest away from the entry point of the radiation, the contact points (12) being isolated with respect to each other by a trench (30) disposed within the layer (28). |
