2-Layer Model for Photopyroelectric Spectroscopy
Christofides, Constantinos; Seas, Antonios (1994)This paper presents a one-dimensional theory which describes the dependence of the photopyroelectric induced signal on the optical and thermal properties of a two-layer sample, for example a thin film deposited on a ...

DEFECTS CHARACTERIZATION OF ARSENIC IMPLANTED SILICON BY AC HALL EFFECT MEASUREMENTS.
Jaouen, H.; Ghibaudo, G.; Christofides, Constantinos (Materials Research Soc, 1986)AC and DC Hall effects measurements as a function of temperature (77-300K) and frequency (1Hz-100KHz) have been performed to characterize implanted Silicon films. This technique enables the determination of the annihilation ...
