(WORLD SCIENTIFIC PUBL CO PTE LTD, 2009)We have prepared the sputtered Ni/n-GaAs Schottky diodes which consist of as deposited, and diodes annealed at 200 and 400 degrees C for 2 min. The effect of thermal annealing on the temperature-dependent current-voltage ... -
Dependence of film thickness on the structural and optical properties of ZnO thin films
(ELSEVIER SCIENCE BV, 2009)ZnO thin films are prepared on glass substrates by pulsed filtered cathodic vacuum arc deposition (PFCVAD) at room temperature. Optical parameters such as optical transmittance, reflectance, band tail, dielectric coefficient, ... -
Dependence of impurity binding energy on nitrogen and indium concentrations for shallow donors in a GaInNAs/GaAs quantum well under intense laser field
(SPRINGER, 2011)Within the framework of the effective-mass approximation, using a variational method, we have calculated the effect of intense laser radiation on the binding energy of the shallow-donor impurities in a Ga1-xInxNyAs1-y/GaAs ... -
The dependence of the intersubband transitions in square and graded QWs on intense laser fields
(PERGAMON-ELSEVIER SCIENCE LTD, 2004)The intersubband absorption in square and graded quantum wells under a laser field is calculated within the framework of the effective mass approximation. We conclude that, for quantum wells with different shapes, the laser ... -
