| 摘要 |
<p>The invention relates to a device comprising at least one p-n diode having a heterostructure, including an HgCdTe substrate that comprises, for each diode: a first portion (4) having a first cadmium concentration; a concentrated portion (11) having a second cadmium concentration greater than the first concentration, thereby forming a heterostructure with the first portion (4); and a p+-doped area (9) located in the concentrated portion (11) and extending into the first portion, thereby forming a p-n junction (10) with an n-doped portion of the first portion (4), referred to as a sole plate (1), characterized in that the concentrated portion (11) is located only in the p+-doped area (9) and forms a casing (12) having a given cadmium concentration.</p> |
