The chapter reviews recent developments in nanostructured semiconductor composites for solar cells. It begins by describing the operating principle of the photovoltaic cell and the strategic potential of nanostructured semiconductors in photovoltaics. The chapter then discusses structured transparent electron ...
Semiconductors have a unique atomic structure that allows for the existence of both electrons and holes. In a semiconductor material, the valence band is filled with electrons, while the conduction band is empty. This creates a band gap, which is the energy difference between the two bands....
In this study, we present the constant light-induced magneto transport (CLIMAT) method, which combines light, electrical current, and a magnetic field (as depicted in Fig.1c) to assess the transport properties of holes and electrons separately. CLIMAT relies on two key elements: (a) determinin...
The negative, or crossed-gap configuration of these quantum wells leads to a charge transfer between the semiconductors InAs and GaSb, generating intrinsic carriers (both electrons and holes) on either side of the interface. This type of quantum well behaves like that of a semimetallic material ...
We demonstrate that it is important to know both the observed fluorescence lifetime (蟿) and the excitation pulsewidth ( Gamma ) in order to determine the ... B Pierce,R Birge - 《IEEE Journal of Quantum Electronics》 被引量: 5发表: 1983年 High-sensitive upconversion optical thermometers de...
(2)to provide two types of charge carriers(electrons and holes)to carry the electrical current or to provide two conductivity types,the n-type(conduction by electrons)and p-type(conduction by holes). The wide range of electrical conductivity makes it possible to control and modulate the magnit...
If an abrupt change in impurity type from acceptors (p-type) to donors (n-type) occurs within asingle crystalstructure, ap-njunction is formed (seeFigure 3Band3C). On thepside, the holesconstitutethe dominant carriers and so are calledmajority carriers. A few thermally generated electrons wi...
Andreev bound states are a superposition of electrons and holes, and can also develop a non-trivial spin structure if the system exhibits spin–orbit coupling and low densities, as is the case in proximitized semiconducting nanowires. Precise experimental characterization of ABSs in proximitized nano...
5) Electrons and Holes in Semiconductors 《半导体中的电子和空穴》 例句>> 6) thermoelectric air conditioner 半导体空调 1. This investigation provides a reference for improving the COP ofthermoelectric air conditioners and reducing their costs.
The quantum mechanical effects such as Fermi pressure, quantum tunneling, and exchange-correlation of holes and electrons in the presence of the magnetic field are considered. The two fluid quantum magnetohydrodynamic model is used to study magnetosonic wave dynamics, while electric and magnetic ...
