n型Hg_(1-x)Cd_xTe光电导体的铟触点若用银浆连接金导线,触点在导电时便有很大的噪声。在任何情况下,把触点作为阴极时,有噪声的触点把电子注入样品;在触点最差的情况下若将其作为阳极,也能注入空穴。用铟焊料把金引线焊接到Hg_(1-x)Cd_xTe样品上,或者用含银环氧树脂连接金引丝和蒸发铟的触点,这个问题就能得到解决, Indium contacts for n-type Hg_ (1-x) Cd_xTe photoconductor If a gold wire is used to connect the gold wire, the contact is very noisy when conducting. In any case, when the contact is used as the cathode, the noisy contact injects electrons into the sample; if the contact is the worst case, it can also inject holes. This problem can be solved by soldering a gold lead to a sample of Hg_ (1-x) Cd_xTe with indium solder or by connecting a gold lead with an epoxy-containing silver and evaporating indium.
