Study The Effect of Classical And Rapid Thermal Annealing on The Electrical Characteristics of P-Ge/P-si Heterojunction
(
Qatar University
, 2002 , Article)
This paper describes the effect of classical thermal (CTA) and rapid thermal annealing (RTA) on the electrical characteristics (I-V, C-V) of isotype Ge/Si heterojunction.
The I-V characteristics were improved after annealing ...
Strain Broadening of E.P.R. Linewidths in Fe/Mgo Single Crystals and Powders
(
Qatar University
, 2004 , Article)
The E.P.R. linewidth of the M= + 1/2 <-» -1/2 transition of Fe3+ spectrum of Fe/MgO single crystals and powders have been measured at 9 GHz before and after annealing. The nominal iron concentrations ranged from 310 to ...
Ionic Conductivity and Ionic Jump Distance of Nuclear Detectors Group CR-39 and BM-355
(
Qatar University
, 2000 , Article)
Electric properties of two nuclear detectors (CR-39 and BM-355) have been investigated as a function of temperature differences. The conductivity appears to be ionic and it was increased with the temperature increase for ...
