Three new sharp lines at 478.6 nm (2.59eV), 483.3 nm (2.565eV) and 486.1nm (2.551eV) were observed in the as-irradiated n-type 6H-SiC samples after neutron, 0.5MeV and 1.7MeV electrons irradations, respectively.
The relation of C_(SC)~(-2)-E of rebar electrode showed linear M-S relationship and positive slope within—0.78—0.37 V(SCE),indicating the passivation film on rebar was n-type semiconductor.
The results indicated that Tet 7.5, 15 and 30 mmol·L -1 inhibited the increase in open time constants and open state probability of L and N type calcium induced by anoxia in concentration dependent manner.
H\-2\|TPR, O\-2\|TPD\|MS and in situ electrical conductivity studies confirmed that the active oxygen species of p\|type semiconductor catalysts were nonstoichiometric oxygen species and the ones of n\|type catalysts were surface lattice oxygen.
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).
The electrical conductivity, Hall coefficient, and magneto-resistance effect of n and p type InSb under temperatures 80-500°K have been measured, the impurity concentrations (after compensation) of samples varying in the range of 4×1013-7×1017cm-3.
This article describes the difference of mobility between N type indium antimonide ingot and the rectaugular sample, which was cut from the ingot on the position where we want to measure the mobility of ingot. This difference exceeds the error of the measurements. Therefore we think this is due to the introduction of the mechanical damage by cutting and grinding. And at the same time it is also due to the introduction of the thermal damage by the preparation of the electrical contacts. They influence ...
The impurity-assisted indirect transition of n-type degenerate Germanium is a second order process. Electrons near the top of the valence band were excited to the (0, 0, 0) valley of the conduction band by the interaction with light and then scattered into the minimum of the conduction band by the short range field of impurity atoms. Using the second order perturbation theory, the absorption coefficient due to such processes was calculated. The fact that contributions of various donors are diffe...
