<p>A device (1) which is responsive to electromagnetic radiation (2) is described. The device comprises an absorption region (6) for electromagnetic radiation and first and second electrodes (5, 7) providing contacts to the absorption region. The absorption region includes a layer (6 1 ) which comprises an aggregation of patterned conductive structures (10), for example periodic structures such as grating and/or spirals, embedded in a radiation-absorbing matrix (11). The conductive structures are configured to increase radiation absorption by the matrix through surface plasmon generation. The conductive structure can be conveniently formed using a lift-off process.</p> |
