An indium antimonide based QWFET（quantum well field effect transistor） with the gate length down to 50 nm has been designed and investigated for the first time for L-band radar applications at 230 GHz. QWFETs are designed at the high performance node of the International Technology road Map for Semiconductors（ITrS）requirements of drive c.r.ent（Semiconductor Industry Association 2010）. The performance of the device is investigated using the SYNOPSYS cAD（TcAD） software. In Sb based QWFET could be a promising device technology for very low power and ultra-high speed performance with 5–10 times low Dc power dissipation.

Major earthquakes of last 15 years （e.g., Northridge 1994, Kobe 1995 and chi-chi 1999） have shown that many near-fault ground motions possess prominent acceleration pulses. Some of the prominent ground acceleration pulses are related to large ground velocity pulses, others are caused by mechanisms that are totally different from those causing the velocity pulses or fling steps. Various efforts to model acceleration pulses have been reported in the literature. In this paper, research results from a recent study of acceleration pulse prominent ground motions and an analysis of structural damage induced by acceleration pulses are summarized. The main results of the study include：（1） temporal characteristics of acceleration pulses; （2） ductility demand spec.r.m of simple acceleration pulses with respect to equivalent classes of dynamic systems and pulse characteristic parameters; and （3） estimation of fundamental period change under the excitation of strong acceleration pulses. By using the acceleration pulse induced linear acceleration spec.r.m and the ductility demand spec.r.m, a simple procedure has been developed to estimate the ductility demand and the fundamental period change of a reinforced concrete （rc） structure under the impact of a strong acceleration pulse.
