Photonic Crystals: Optical Materials for the 21st Century be investigated by an appropriate multi-scale analysis utilizing Bloch waves as carrier waves together with an adaptation of .·.-perturbation theory. This leads to a natural generalization of the slowly varying envelope approximation to the case of nonlinear wave propagation in PCs.dictator 发表于 2025-3-27 04:07:38
ZnO Metal Organic Vapor Phase Epitaxy: Present State and Prospective Application in Optoelectronics tes will be described. Diethyl-zinc (DEZn) and an alcohole has been used as Zn- and oxygen precursor, respectively. The ZnO MOVPE layers have been analyzed by a variety of techniques, including HRXRD, PL, CL, CV, Hall and AFM.ANN 发表于 2025-3-27 07:08:24
Probing the Conduction Channels of Gold Atomic-Size Contacts: Proximity Effect and Multiple Andreev y a single atom between the electrodes contributes one channel to the transport as predicted by different theoretical models. The analysis of the transport channels of retraceable opening and closing procedures gives additional evidence that the transport channels are determined by the properties of the central atom.Spirometry 发表于 2025-3-27 12:38:12
Metal-Insulator Transitions at Surfacesodel and the Weiss mean-field theory for the Ising model, are found to be formally equivalent. A new kind of surface state appears in the low-energy part of the one-particle excitation spectrum as a precursor effect of the Mott transition.Indicative 发表于 2025-3-27 14:39:14
https://doi.org/10.1007/978-3-642-12848-6 higher stability of QDs against high current injection as compared to quantum wells. High reflectivities of above 99 % for undoped and p-type doped distributed Bragg reflectors based on ZnSe and MgS/ZnSe superlattices have been obtained. Monolithic vertical resonators possess a quality factor of about 100.definition 发表于 2025-3-27 19:33:21
Andrew Hogue,Michael R. M. Jenkinthms. In order to show the presence of contact-dependent features in the molecular conductance, we discuss three archetypal molecular devices, which are intended to focus on the importance of the different sub-parts of a molecular two-terminal setup.NIP 发表于 2025-3-27 22:49:34
