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 ...
A Rational Exponential Model for Unconstrained Non-Linear Optimization
(
Qatar University
, 2002 , Article)
In this Paper, a new algorithm based on the non-quadratic model is suggested for solving unconstrained optimization problems which modifies the classical conjugate gradiant methods. This technique has the same properties ...
