Impurity gettering
WitrynaAbstract Since the early 1960s gettering has been a common method to reduce unintentional metal impurities in the electrically-active zones of semiconductor … Witryna8 paź 2013 · Impurities (Li, Na, and K) were shown to getter in as-grown CdTe/Si epilayers at in situ Te-stabilized thermal anneal (~500°C) interfaces. In HgCdTe/CdTe/Si epilayers, indium accumulation was observed at Te-stabilized thermal anneal interfaces. Impurity accumulation was measured at HgCdTe/CdTe and CdTe/ZnTe interfaces.

WitrynaTherefore, impurity gettering has been widely studied to reduce their deleterious effect. Several methods have been investigated, including spontaneously occurring and intentionally formed sinks for the transition metals—at the surface and bulk. Depending on where we capture metal impurities, it is classified to intrinsic and extrinsic gettering. Witryna1 maj 2024 · Gettering is the process of removing metallic impurities to a less harmful region of the device, and is therefore an essential aspect of the cell fabrication process.
