buffer layer

A thin n-type buffer layer is added on top of the absorber.

Another way to use materials of different lattice constants is to place a buffer layer between them.

GaN with a high crystalline quality can be obtained by depositing a buffer layer at low temperatures.

Therefore, SiO has to be covered with an extra buffer layer prior to the tungsten deposition.

Thus, the buffer layer used is Cd-free which eliminates the worries related to the toxicity and environmental impact of Cd.

It has been proposed to replace the hazardous cadmium sulfide, CdS, as a buffer layer in solar cells.

ZnS nanodots have been used as passivation layers-point contact buffer layers in chalcopyrite based thin film solar cells.

One close look had shown her Anna DeBlass was skimming under the edge of emotion on a buffering layer of chemicals.

Chu used resistive tin oxide as the buffer layer and then thinned the CdS from several micrometres to under half a micrometre in thickness.

In practical fibers, the cladding is usually coated with a tough resin buffer layer, which may be further surrounded by a jacket layer, usually glass.

The cyclical nature of this process makes it similar to atomic layer deposition (ALD), which is also used for buffer layer deposition.

This makes YN a possible buffer layer between a substrate and the GaN layer during GaN crystal growth.

This was done when he added an intervening or buffer layer to the TCO/CdS/CdTe stack and then thinned the CdS to allow more light through.

It is a sequential and cyclic process that enables the deposition of semiconductor thin films, mainly for (although not restricted to) photovoltaic applications, specially chalcopyrite absorber layers and buffer layers.

The buffer layer is made of AlInAs, with the indium concentration graded so that it can match the lattice constant of both the GaAs substrate and the GaInAs channel.

Fortunately, the handlers were regular hangar personnel, and since they had known the cartons were Gorren's and valuable, they had placed them on a top layer, fifth stack, with buffering layers on either side.

Different techniques, such as carrier lifetime control, injection efficiency and buffer layer devices, have been used to minimize turn-OFF switching transient, but all result in a trade-off between the ON-state loss and switching speed.

Buffer layers for chalcopyrite-based thin film devices: Replacement of the standard CdS by ecologically more favorable materials (InS, Zn(O,S) etc.) deposited using Spray-ILGAR on different absorber materials.

Dr. Antonio Mogro-Campero and Larry G. Turner deposited the superconducting film on a silicon wafer by placing a buffer layer of zirconia, an oxide of the metal zirconium, between the superconducting material and the silicon.
