In a previous paper we have suggested that for VLWIR QWIP operating in the tunnelling regime, the dark current mostly results from the interaction between the

The  variety of cadmium hydroxide (brucite-type structure) as a starting material does not allow diagram study at room temperature because of its high stability.. More recently,

By employing an externally injected NIR beam, E NIR , that is resonant with the interband transitions of the quantum wells in the QCL, the nonlinear susceptibility is

conducteur pur avec des éléments étrangers, on peut influencer dans une large mesure le niveau de Fermi ainsi que la conductivité électrique. Ces atomes de dopage sont incorporés

This system was chosen as it is useful in infrared emission, finally, we introduce the optimum structure of quantum well to obtain the maximum optical gain, at room temperature

Although President Richard Nixon of the United States visited the People ’s Republic of China in February, 1972, which marked a great step forward in the

During a collision : (a) the total linear momentum is conserved at each instant of the collision ; (b) the kinetic energy conservation (even if the collision is elastic) applies
