Cathodoluminescence Microscopy of Inorganic Solids

Autor: B.G. Yacobi, D.B. Holt

Microcharacterization of materials is a rapidly advancing field. Among the many electron and ion probe techniques, the cathodoluminescence mode of an electron probe instrument has reached a certain maturity, which is reflected by an increas ing num

Modeling of helix reversal defects in polytetrafluoroethylene

Autor: D.B. Holt, Barry L. Farmer

Publikováno v: Polymer. 40:4673-4684

Molecular mechanics and dynamics simulations have been utilized to probe the nature of helix reversal activity in polytetrafluoroethylene (PTFE). The results of the simulations indicated that helix reversals do form and migrate in PTFE crystals. At l

EBIC studies of grain boundaries

Autor: B. Raza, D.B. Holt, A. Wojcik

Publikováno v: Materials Science and Engineering: B. 42:14-23

REBIC is a powerful technique for the study of defects, especially grain boundaries (GBs), in ill developed, high-resistivity (semi-insulating) materials. Ideas for modelling GB REBIC contrast have been proposed but neither quantitatively developed n

Study of misfit dislocations by EBIC, CL and HRTEM in GaAs/InGaAs lattice-strained multi-quantum well p-i-n solar cells

Autor: J.S. Roberts, R. Grey, Paul Griffin, J. Barnes, A. G. Norman, Keith W. J. Barnham, John L. Hutchison, Massimo Mazzer, D.B. Holt, E. Grunbaum, John P. R. David

Publikováno v: Materials Science and Engineering: B. 42:43-51

The location, density and nature of misfit dislocations (MDs) in lattice-strained multi-quantum well (MQW) structures were investigated by depth-resolved electron-beam-induced current (EBIC) and cathodoluminescence (CL) modes in a scanning electron m

Properties and structure of antiphase boundaries in GaAs/Ge solar cells

Autor: Giancarlo Salviati, Laura Lazzarini, Lucia Nasi, M. Mazzer, C. Hardingham, D.B. Holt, C. Zanotti-Fregonara

Publikováno v: Materials Science and Engineering: B. 42:204-207

Antiphase boundaries (APBs) are particularly crystallographically simple but technologically troublesome boundaries that tend to occur in profusion in GaAs grown epitaxially on (100) oriented substrates of Ge or Si. APBs were found to form only in a

Quantitative studies of beam-induced defects in III–V compounds by cathodoluminescence and transmission electron microscopy

Autor: M. Urchulutegui, D.B. Holt, Laura Lazzarini, Giancarlo Salviati, E. Napchan

Publikováno v: Materials Science and Engineering: B. 24:130-134

Electron beam currents above 1 μA induce long straight dislocations lying just below the surface in (001) wafers of GaAs and InP. These dislocations are of interest in themselves and are well situated for cathodoluminescence (CL) dark contrast studi
