We present new statistical results on the spectral index-flux density relation for large samples of radio sources using archival data of the most sensitive surveys, such as 6C, Miyun, WENSS, b3, NVSS, Gb87. Instrumental selection effects and the completeness of the catalogs are discussed. based on the spectral indices calculated for about 200 000 sources from the WENSS (327 MHz) and NVSS (1.4 GHz) catalogs, we obtained (1) The median spectral index increases from amed --0.9 toαmed --0.8 (Svαvα), while S327 flux densities decrease from 0.1 Jy down to 25mJy. The median spectral indices nearly show no variation within the error bars when the flux density is larger than 0.1 Jy. (2) A dependence of the fraction of ultra-steep spectrum sources (USS, -1.5 p spectrum sources (SSS, -1.0 pectrum sources (FSS, -0.5≤α≤0.0) is partly responsible for the spectral flattening. Another contribution to the spectral flattening comes from the variation of αmed of steep spectrum sources (αpectral flattening for faint sources (down to S327- 20mJy) with steep spectra (αpectral selection effect occurs when spectral indices are calculated from samples with a large frequency separation.

An improved vertical power double-diffused metal–oxide–semiconductor（DMOS） device with a p-region（p1） and high-κ insulator vertical double-diffusion metal–oxide–semiconductor（HKp-VDMOS） is proposed to achieve a better performance on breakdown voltage（bV）/specific on-resistance（Ron,sp） than conventional VDMOS with a high-κ insulator（CHK-VDMOS）.The main mechanism is that with the introduction of the p-region,an extra electric field peak is generated in the drift region of HKp-VDMOS to enhance the breakdown *** to the assisted depletion effect of this p-region,the specific on-resistance of the device could be reduced because of the high doping density of the N-type drift ***,based on the superposition of the depleted charges,a closed-form model for electric field/breakdown voltage is generally derived,which is in good agreement with the simulation result within 10% of *** HKp-VDMOS device with a breakdown voltage of 600 V,a reduced specific on-resistance of 11.5 Ωm·cm^2 and a figure of merit（FOM）（bV^2/Ron,sp）of 31.2 MW·cm^-2 shows a substantial improvement compared with the CHK-VDMOS device.
