An NMR study of bistable defects in CdTe and CdF₂

Creator:

Shroyer, Mark H.

Abstract:

Bistable properties have been reported in CdF₂ and CdTe systems doped with In and Ga. It is characteristic of these materials that the excited bistable state can be accessed by optical excitation. In this work, pulsed nuclear magnetic resonance (NMR) in conjunction with illumination at low temperatures has been used...

Indium donor/metal vacancy defect complexes in Cadmium Telluride studied with Perturbed Angular Correlation Spectroscopy

Creator:

Griffith, John W.

Abstract:

Semi-insulating, powder samples of Cadmium Telluride (CdTe) have been studied using ¹¹¹In Time Differential Perturbed Angular Correlation (PAC) Spectroscopy. The samples have been lightly doped (~10¹² cm⁻³) with ¹¹¹In atoms, which occupy well-defined metal (Cd) lattice sites and act as probes of the local environment. These substitutional donors form a...
