A correlation between electron traps and growth processes in n-GaAs prepared by molecular beam epitaxy

Abstract
By using a single Knudsen source independently to generate molecular beams of As2 and As4 from elemental arsenic, a direct correlation has been observed between the arsenic species used and deep level concentrations in molecular beam epitaxy grown n‐type GaAs films. Some preliminary observations on comparative growth temperature effects and Ge site occupancy are also reported.
