We propose a simple quantum structure which exhibits resonant tunneling under one bias and simple tunneling under the opposite one, thus acting as a rectifier. The diode consists of a single laterally-indented barrier. Due to its particular conduction-band ...
The photoelectrochem. behaviors of dye-sensitized nanoporous TiO2 solar cells are studied under influences of light intensity, redox couple concn., temp., different cations and water in the nonaq. soln. The value of the ideality factor of dyed nanoporous T ...
Combination approaches provide an interesting way to improve adaptive filter performance. In this paper, we study the mean-square performance of a convex combination of two transversal filters. The individual filters are independently adapted using their o ...

The aim of this paper is to present a universal power quality conditioning system (UPQS) which consists of a unified power quality conditioner (UPQC) extended by adding a shunt active filter at the load side. Such system has heiger harmonic compensation ch ...
The aim of this letter is to present a universal power quality conditioning system (UPQS) named after unified power quality conditioner (UPQC), which is extended by adding a shunt active filter at the load side. Its main purpose is to compensate for supply ...
In this paper, a high quality single-phase rectifier with reduced ripple of the input current is proposed. the chosen solution has the main advantage of reducing cither the current ripple or the operating switching frequency, by a compensation effect of tw ...
PFC rectifiers are more and more used as front end circuits for low and mid sized apparatus. Especially for the eigh current applications, the size and weight of passive components are an imprtant factor, also for the economic aspect. The number and size o ...
Junctions between n-type semiconductors of different electron affinity show rectification if the junction is abrupt enough. With the advent of 2D materials, we are able to realize thin van der Waals (vdW) heterostructures based on a large diversity of ma ...
The aim of this paper is to present a universal power quality conditioning system (UPQS) which consists of a unified power quality conditioner (UPQC) extended by adding a shunt active filter at the load side. Such system has higher harmonic compensation ch ...
Poling of calcium and zirconium modified lead titanate pyroelelectric thin films has been studied, Poling temperature and electrical field were optimized to achieve high figure of merits. It was found that thermal activation is important to obtain highly p ...
