Influence of Annealing on the Electrical Properties of Semi-Insulating GaAsrsion is attributed to manganese. Si.N. coated wafers, heat-treated in standard conditions for ion implantation post-annealing, do not show manganese and their electrical behaviour involves the balance of both shallow and deep levels present in the as-grown crystal.作者: 和諧 時間: 2025-3-27 23:14 作者: shrill 時間: 2025-3-28 04:27 作者: 拱墻 時間: 2025-3-28 06:48
Heat Treatment Behaviour of Cr Implanted in GaAs SI Material. The presence of a deeper structure for both types of heat treatment shows how important is the influence of the defects on the Cr diffusion mechanism. In the case of face to face annealing, the tail of the Cr distribution demonstrates that in-dif fusion takes place.作者: 切割 時間: 2025-3-28 11:56

The Influence of Substrate Properties on the Electrical Characteristics of Ion-Implanted GaAsimplanted and annealed layers. Certain Cr-doped semi-insulating substrates exhibit a marked decrease in sheet resistance during the anneal cycle. We find that the carrier concentration of the converted material increases with the background Si concentration in the starting material.
