Improvement in electroabsorption and the effect of the electric field in the tuneable wavelength converter
(1999)The numerical results of the study of a novel wavelength converter which can be tuned with the application of an external field are presented. For this device, exciton binding energies, radiuses and the absorption coefficient ... -
Lie Ideals of Semiprime Rings with Generalized Derivations
(2018)Let R be a 2-torsion free semiprime ring, U a noncentral square-closed Lie ideal of R. A map F:R?R is called a generalized derivations if there exists a derivation d:R?R such that F(xy) = F(x)y + xd(y) for all x,y?R. In ... -
LIPOLYTIC ACTIVITY OF LACTIC ACID BACTERIA ISOLATED FROM TURKISH PASTIRMA
(2018)Lipases are widely distributed in nature and catalyze the hydrolysis of mono, di and tri acyl glycerols to liberate free fatty acids and glycerol. Various microorganisms produce lipases either alone or together with esterase. ... -
The orbit center dependence of the energy levels in a multiple quantum wells under external tilted magnetic and electric fields
