On the basis of a method of statistical modeling investigations of basic mechanisms of dispersion in semiconductor heterostructures and basic characteristics of a physical process of carrier transfer in a mode with occurrence of plasma waves are carried out. Novelty consists in statistical modeling and self-co-ordinated solution of Schroedinger equation. It all allows revealing of basic physical mechanisms,...
We develop the discrete derivatives representation method (DDR) to find the physical structures of the Schrodinger equation in which the interpolation polynomial of Bernstein has been used. In this paper the particle swarm optimization (PSO for short) has been suggested as a means to improve qualitatively the solutions. This approach is carefully handled and tested with a numerical example.
Silicon nanowire (SiNW) based devices have aroused great interest since they exhibit high carrier mobilities and sub-threshold slopes close to 69 mV/decade due to good charge control. The charge in the nanowire channel is obtained by solving the Poisson equation self-consistently with the Schroedinger equation. However this is a very computationally expensive process and it is usually preferable to...
We present a new self-consistent Maxwell-Schroedinger technique with the aim to analyze the electromagnetic field dynamics together with the quantum phenomena of carbon nanotubes. The Maxwell equations, discretized by the Transmission Line Method in a three-dimensional domain, are coupled to the Schroedinger equation and simultaneously solved. We study the dynamic of a wavepacket along a nanotube...
In this paper we present a novel technique in which the Maxwell equations, discretized by the Transmission Line Method in a three-dimensional domain, are coupled to the Schroedinger equation and simultaneously solved. The goal is to develop a method that accounts for deterministic electromagnetic field dynamics together with the quantum phenomena, which are typical of nanotube transistor devices....
We consider 2D microwave open cavities whose ray dynamics is chaotic. In particular, we estudy theoretically and experimentally, cavities which yield mixed (chaotic ad regular) phase space. Such cavities are connected to leads to form electromagnetic waveguides with single or multiple cavities. The principal feature of mixed chaos is the existence of islands of stability (resonance islands) in phase...
