The structural and spectroscopic properties of Na_2O-Al_2O_3-SiO_2-xP_2O_5 glasses(x = 0 to 7 mol%) are investigated.Both Raman and IR spectra reveal that discr
Single event gate rupture(SEGR) is a very important failure mode for power MOSFETs when used in aerospace applications,and the cell regions are widely considere
ZnO thin films were synthesised by a new method which uses polyvinyl alcohol (PVA) as the polymer precursor. The films are annealed at different temperatures an
In the fiber optical synthetic aperture (FOSA) system, the diffraction of the Gaussian beam limited by the aperture in exit pupil plane of fiber collimator is s
