|Title:||ALUMINUM IN HYDROGENATED AMORPHOUS-GERMANIUM|
|Abstract:||The effects of aluminium on the electro-optical properties of high quality sputtered hydrogenated amorphous germanium are reported. Two distinct effects are found: at low concentrations, the aluminium atoms act as active p-type dopants making the Fermi level shift towards mid-gap compensating the intrinsically n-type material. At higher concentrations, a hydrogenated germanium-aluminium alloy is formed. The optical gap shrinks and transport is probably dominated by holes.|
