Hole mobilities of quantum-well p-MOSFETs on strained Si (sSi)//strained SOI (sSOI) and heterostructure substrates are investigated as a function of temperature. Ge interdiffusion during annealing in highly strained on SOI is reduced by the growth of layer on...
An optical fiber sensor system that can be installed and used to give reliable and informative data has been developed, tested and evaluated for the past two years on a 50 year-old concrete foot bridge of known conditions. Besides environmental monitoring, the bridge has been subjected to different loading and specific damages have been induced. The evolution of the bridge has been recorded using...
We report on n-channel tunneling field-effect transistors (TFET) with a tensile strained Si channel and a compressively strained Si0.5Ge0.5 source. The device shows good performance with an average subthreshold swing S of 80mV/dec over a drain current range of more than 3 orders of magnitude. We observed that an applied back-gate bias increases the on-current by a factor of 1.6, and improves the off-current...
The LED device for illumination in space application has been well done in the past few years, including the in cabin application on bio-science satellite in 2007 and out cabin application on spacecraft in 2008 to shine on the first human step in space of Chinese astronaut. The thermal property of assembled LED lamp has been experimentally characterized by a recently developed spectroscopy method,...
0.99[(NaxK1-x)Nb0.955O3-0.045LiSbO3]-0.01CaTiO3 (NKNLS-CT) lead-free piezoelectric ceramics have been prepared by the conventional mixed oxide method. The effect of the K/Na ratio on the electrical properties of NKNLS-CT ceramics was investigated. When x = 0.52, the ceramics possess optimum properties: piezoelectric constant d33=266 pC/N, planar electromechanical coupling factors kp=48.7 %. These...
The new lead-free ferroelectrics with composition of 0.995[(K0.5Na0.5)0.95Li0.05](Nb0.95Sb0.05)O3-0.005BaTiO3 (0.995KNLNS-0.005BT) were prepared by using normal sintering method, and the ferroelectric relaxor behavior and electrical properties of the ceramics were systematically studied. The ceramics exhibit typical ferroelectric relaxor behavior, that is, the dielectric peaks become increasingly...
