Nanoscale Schottky barrier MOSFETs (SBFETs) are explored by solving the two-dimensional Poisson equation self-consistently with a quantum transport equation. The results show that for SBFETs with positive, effective metal-semiconductor barrier heights, the on-current is limited by tunneling through a barrier at the source. If, however, a negative metal-semiconductor barrier height could be achi...
Under commercial conditions, weaning of piglets is associated with social, environmental and dietary stress. Consequently, small-intestinal barrier and absorptive functions deteriorate within a short time after weaning. Most studies that have assessed small-intestinal permeability in pigs after weaning used either Ussing chambers or orally administered marker probes. Paracellular barrier functi...
In this paper we demonstrate a new method for microfabricating PDMS devices that controls vapour diffusion, thereby reducing water loss at elevated temperatures and greatly increasing the reliability of the PCR. In the past, the vapour and liquid diffusion properties of the P t b m t t ©
Three Bi2Sr2CaCu2O8 single crystals with dierent annealing processes have been measured in terms of complex AC susceptibilities vn vn ÿ iv00 n (n 1; 3) to reveal the eect of ̄ux-pinning strength. The third harmonic susceptibility changes dramatically when the pinning strengths are dierent due to dierent annealing processes, although the fundamental susceptibilities are quite similar. Th...
