Petrov) Light-induced charge transmission through a molecular junction (molecular diode) is studied in the framework of a HOMO–LUMO model and in using a kinetic description. Expressions are presented for the sequential (hopping) an...
We report on the fabrication and characterization of the first p-n diode made from a heterojunction of epitaxial p-type Ge0:998C0:002 on an n-type Si substrate. Epitaxial Ge0:998C0:002 was grown on a (100) Si substrate by solid source molecular beam epitaxy. The p-GeC/n-Si junction exhibits diode rectification. The I-V characteristics of the p-GeC/n-Si diode indicate a reasonable reverse satura...
Background and Aim: Diode laser is a great choice for soft tissue surgery. The diode laser is partially absorbed by hard dental tissues, making it safe for soft tissue surgery. This study aimed to compare the tissue thermal changes induced by three types of diode lasers at 810, 940, and 980nm wavelengths. Materials and Methods: In this in-vitro experimental study, using a diode laser device (c...
We simulate numerically the classical charge dynamics in a microscopic, planar, vacuum diode with finite emitter area and number of electrons gap. assume that are emitted under space-charge limited conditions fixed potential applied to diode. The Coulomb interaction between all is included using method molecular dynamics. compare our results conventional 2-D Child-Langmuir explain how it applic...
Since 1998, we have developed two balloonborne diode laser spectrometers, SDLA and micro-SDLA, to yield in situ concentration data of H2O in the middle atmosphere by absorption spectroscopy in the 1.39mm spectral range. In this paper, we revisit the molecular parameters, line intensities and pressurebroadening coefficients, for several lines of the n1+n3 and 2n1 bands, which are useful for the ...
Background and Aim: Bacterial disinfection is considered as the primary etiology of pulpal and periapical lesions and as the result, adequate elimination of such infections is one of the purposes of root canal treatment; But since this purpose is impossible to achieve, reducing the bacterial load seems to be as a rational goal. Diode lasers have made their way into endodontics for better disinf...
