Sentence examples for barrier composition from inspiring English sources
Dark current vs. bias, photoresponse, quantum efficiency, lifetime, and modeling are used to correlate device performance with the wide gap barrier composition.
In addition to larger intersub-band oscillator strength, these detectors afford greater flexibility than extrinsically doped semiconductor infrared detectors because the wavelength of the peak response and cutoff can be continuously tailored by varying layer thickness and barrier composition.
Improving these devices requires greater control of the InAs quantum well properties, which in part, are related to the strain induced from the substrate material, buffer layer thickness, barrier composition, doping, and the heterointerface.
The main differences between the two structures are the doping profile, the doping concentration, and the barrier composition of the triangular well.
This improvement is usually attributed to smaller leakage currents due to the higher conduction band offset for x= 0.45, since the QCLs for the two barrier compositions are designed in such a way that the population ratios ρp for the laser levels are the same.
The barrier solvent composition was optimized and the chemical composition of fractionated polymer chains was investigated as a function of barrier solvent strength using an online Fourier-transform infrared (FTIR) detector.
At the optimum barrier solvent composition, this method can be applied to separate effective HDPE segments from the other components, which has been demonstrated using an experimental OBC sample.
The ground-exciton binding energy as a function of x Al 1 (Figure1b) shows initially a decreasing behavior until the left-hand-barrier Al composition is approximately 0.18.
With hydrostatic pressure applied, the ground state-related exciton binding energy keeps decreasing along the whole range of the left-hand-barrier Al composition values.
Figure1 shows the dependence of the ground (n e = 1 and n h = 1) exciton binding energy as a result of the variation of the left-hand-barrier Al composition x Al 1.
Efficient homeostatic mechanisms established by those two barriers control composition of brain extracellular fluids, the ISF and CSF.
