Abstract: (Voir fig. 1)  Dispositif à semi-conducteur servant à détecter le rayonnement.  Il comprend plusieurs couches de puits quantique, comprenant chacune des états excités et de masse de liaison, qui sont intercalées avec plusieurs couches limites de super-réseau ayant chacune une mini-bande d'états d'énergie.  Selon le choix de l'épaisseur et de la composition des couches, les états excités du puits quantique ont des énergies qui sont à peu près égales aux énergies des états des mini-bandes.  Les états excités et les mini-bandes forment une bande d'états d'énergie essentiellement continue à travers les nombreuses couches.  Des porteurs sont excités depuis les états de masse du puits quantique jusqu'aux états excités par absorption de photons, et sont balayés dans et à travers les mini-bandes par un champ électrique appliqué extérieurement.  Les porteurs sont recueillis comme courant photoélectrique.  Les états excités peuvent être positionnés de façon sélective dans les mini-bandes afin d'individualiser les propriétés des dispositifs qui peuvent comporter des dopants de type N et de type P.  Les dispositifs répondant à plus d'une gamme de longueurs d'onde sont également décrits.

Abstract: A thermal imaging device (10) includes a housing (130) defining a battery compartment, and carrying a door portion (166) closable over this battery compartment to provide environmental protection. The battery compartment door (166) includes a spring-loaded latching device (170) which will maintain the door (166) sealingly closed under normal use conditions of the device (10). However, in the event that a battery (124) received in the compartment should vent gasses sufficient to pressurized the compartment to a selected level, the latching device (170) will yield to allow a slight opening of the door (166) and a controlled venting of these gasses to ambient. Controlled venting of the battery gasses additionally occurs at a location of the device (10) remote from the user, and the battery compartment door (166) is itself interposed between the user and the venting battery (124).
