| 摘要 |
<p>The invention relates to an optronic window (100) which comprises a substrate (10) having two surfaces (11, 12). The window comprises, on one of the surfaces of the substrate or on both surfaces thereof, a stack of a plurality of heterostructures (30), each heterostructure consisting of at least two semiconducting layers (31, 32), SC1 and SC2, the SC1 layer (31) being doped, the SC2 layer (32) in turn comprising a two-dimensional electron-gas layer (33) formed at the interface with the SC1 layer. The window further comprises an electrode (40) contacting all the electron-gas layers (33), a biperiodic metal grating (50) embedded in the stack so as to contact the electrode (40). The substrate and the layers are transparent in the 0.4 pm to 5 µm band.</p> |
