Based on the theory of glow discharge, the angle distribution of electron and the recombination process are simulated by adopting Monte Carlo method. The doping process of n-type diamond film is investigated by this method for the first time.
CdIn2O4(CIO)thin film,n-type ternary mental oxides thin film materials, has attracted much attention for its excellent optical and electrical properties and foreground for comprehensive application, and become a hot point in the research field of transparent conducting oxides(TCO) thin film.
Cd2SnO4 (CTO) films prepared by rf reactive sputtering from a Cd-Sn alloy target in Ar-O mixtures was found to be an n-type, defect and degenerate semiconductor in which oxygen vacancies provide the donor states and free-carrier concentration is up to 4.46×1026 m-3. The films were annealed at temperature up to 500℃ in stable Ar flow.
It is discussed that the capacityvoltage (CV) characteristics of the metalferroelectricsemiconductor (MFS) structure using semiconductor theory. The result shows that on the nSi,the CV curve of ideal MFS structure is counter clockwise and CV curve of carrier injected MFS structure is clockwise,which is agreement with the experiment.
Since wavelet bases are not available for this general setting, the new idea used here is to apply the discrete Calderón-type reproducing formula associated to para-accretive functions developed in [14].
However, the ECV measurement of dopant concentration in the underlying lightly doped n-type substrate is significantly influenced by the upper heavily-doped layer.
Segmentation of p-n junction was performed by implantation of boron (for the n-type Ge) and mechanical grooving of the Li diffusion layer (for the p-type Ge).
Dense and rigid n-CdS films are deposited by electron beam technology. The morphology of these films prior and after etching has been examined by scanning electron microscope. Having improved the structure of the evaporating chamber the sputtering phenomenon of the CdS grains has not been observed. Diffusion of Cd++ and Gu+ ions towards them opposite sides from the heterojunction has been determined by ionic probe method. The main characteristics of cells made from these evaporated films are: Isc -25mA/cm2,...
In this paper,it is reported that indium tin oxide (ITO) thin films were prepared by an electron beam technique.As these films are degenerate n-type semiconductors,they are used as a window material in heterojunction solar cells.The effect of heat treatment (300℃) in various environments.(H2,N2,Ar or air) on the electrical and optical properties of ITO prepared films has been investigated.As the resistivity is decreased and optical transparency is increased by heat treatment in H2 or Ar especially.A sheet r...
In this paper,a new preparation method for SnO2 transparent electro-conductive film atmospheric evaporation-thermal decomposition from aqueous solution,was presented.Some of its properties were characterized.It is suggested that this method is more simple in preparation of the transparent electro-conductive film of SnO2 on surfaces with any shapes in comparison with a number of known methods.The results obtained with XDS,AES and ESCA indicated that a oxygendefected SnOj-,film with n-type semiconductor was f...
