Relaxation effects on the negatively charged Mg impurity in zincblende GaN
(1999-11-01)
The electronic structure of Mg impurity in zincblende (c-)GaN is investigated by using the ab initio full potential linear-augmented plane-wave method and the local density-functional approximation. Full geometry optimization ...
Sleep homeostasis in rats assessed by a long-term intermittent paradoxical sleep deprivation protocol
(Elsevier B.V., 2005-05-28)
Numerous studies have evaluated the sleep homeostasis of rats after short- or long-periods of sleep deprivation, but none has assessed the effects of prolonged sleep restriction on the rat's sleep pattern. the purpose of ...

ELECTRONIC BAND STRUCTURE OF THE ORDERED Zn0.5Cd0.5Se ALLOY CALCULATED BY THE SEMI-EMPIRICAL TIGHT-BINDING METHOD CONSIDERING SECOND-NEAREST NEIGHBOR
Aunque la descripción de las aleaciones ternarias semiconductoras se hace tradicionalmente asumiendo la aproximación de compuesto pseudo-binario. Para el caso de aleaciones artificiales de compuestos II-VI y III-V, en las ...

Optical band-gap determination of nanostructured WO3 film
(2010)
The optical band-gap energy of a nanostructured tungsten trioxide film is determined using the
photoacoustic spectroscopy method under continuous light excitation. The mechanism of the
photoacoustic signal generation is ...

Cálculo y comparación de la estructura electrónica de los superconductores de alta temperatura crítica, YBa2Cu3O7 e YBa2Cu4O8
(Universidad Nacional Mayor de San MarcosPE, 2007)
La superconductividad es el fenómeno que se da en algunos materiales metálicos y cerámicos. Se caracteriza por tener resistencia cero y ser diamagnéticos puros, presentándose a temperaturas menores a la temperatura critica. ...
Analysis of electronic structure and X-ray absorption and emission spectra in MgO within the FP-LAPW method
(Sciencedomain international, 2018-10-05)
In this work we calculated MgO ab initio X-ray Absorption and Emission spectra using the Full Potential Linearized Augmented Plane Wave method within the Density Functional Theory formalism. The X-ray Absorption and Emission ...
