Structural defects in bulk and epitaxial CdTe

Materials Science and Engineering: B, 1993
The advantages of growing bulk CdTe from the vapour are summarized and the structural defects present in material grown using three different vapour methods compared critically. Kawano's growth rate explanation of twin distribution is developed and the effect of growth conditions in anomalous cases is speculated upon.

Signatures of the Effects of Defects on the Bulk Moduli of Crystalline Solids

SSRN Electronic Journal, 2020
Abstract The small atomic region containing a defect in a crystalline solid is nonlinear elastic. In this paper, we consider a solid containing defects as a composite wherein the defected regions have a bulk modulus, K , different from that of the perfect crystal.

Passivation of Surface and Bulk Defects in InP

MRS Proceedings, 1992
ABSTRACTThe effect of sulfur and hydrogen plasma treatment on the Schottky barrier and photoluminescence (PL) properties of p-InP is reported. Both the treatments increase the barrier height of Au/p-InP diodes and band to band PL. This is explained as being due to a shift in the surface fermi level position towards the P vacancy related pinning level ...

The Interaction of Bulk Defects with Surface Reconstructions

MRS Proceedings, 1991
ABSTRACTIt is demonstrated by ultra-high vacuum transmission electron microscopy that subsurface dislocations and stacking faults strongly interact with the Au (001) (5×n) surface reconstruction. This effect is found in both bulk single crystal and thin fílm samples.

Electronic Structure of Bulk and Defected CaCu3Ti4O12

ECS Transactions, 2006
The calcium copper titanate CaCu3Ti4O12 is a distorted perovskite exhibiting a giant dielectric constant with non-ferroelectric temperature behavior. Recent investigations tend to attribute the origin of the anomalous behavior of CaCu3Ti4O12 dielectric properties to the presence of heterogeneous microstructure and grain boundary layers, excluding that ...

NATIVE DEFECT COMPENSATION IN III-ANTIMONIDE BULK SUBSTRATES

Selected Topics in Electronics and Systems, 2004
As-grown, undoped III-antimonide bulk substrates contain high concentration of native defects resulting in high residual carrier density. In this paper, we have demonstrated that native defects can be compensated in bulk substrates of GaSb , InSb , and Ga 1-x In x Sb via impurity doping and low temperature growth from nonstoichiometric melts and ...

Structural Techniques for Bulk Defects Characterization

1982
This lecture considers briefly the most widely applied structural techniques for the characterization of crystal defects in silicon, like X-ray topography, transmission and scanning electron microscopy. Examples of defects analysis are reported concerning the characterization of the defects introduced by the phosphorous predeposition in Si and the ...
