The novel trench junctionless poly-Si thin-film transistor (trench JL-TFT) with ultra-thin body (2.4 nm) is utilized to simple dry etching process. This novel devices show excellent performance in terms of steep SS (99 mV/dec.) and high I ON /I OFF (>107). The I ON current of the ultra-thin body (UTB) JL-TFT is increased by quantum confined effect.

Tunneling of seismic body waves through thin high-velocity layers in complex structures
Studia Geophysica et Geodaetica, 1992The hybrid ray-reflectivity method is applied to the problem of the transmission of the reflected wave field through a thin high-velocity layer (or through a thin stack of high velocity layers), situated in the overburden of the reflector. In the hybrid ray-reflectivity method, the standard ray method is applied in the smooth parts of the model, and ...

SummaryThis article deals with fast transient phenomena involving fluids and structures undergoing large displacements and rotations, associated with nonlinear local behavior, such as plasticity, damage, and failure. A new approach is proposed to handle the interaction between a structure and the compressible fluid it is immersed into.

Abstract The effect of quantum confinement has become significant in terms of its impact on the scalability and electrostatics of ultra-thin-body double-gate MOSFETs. In this paper, we present a simplified model to account for the effect of quantum confinement, considering the contribution of the ground-state and the first excited state ...

At the conceptual design stage, the cross-sectional shapes of thin-walled beams (TWBs) need to be optimized to improve the performance of automobile structure. Therefore, this paper innovatively proposes a cross-sectional shape optimization method to acquire a low cost, high stiffness, manufacturable and lightweight TWB. Meanwhile, the stamping cost of

The spot welded sections of automobiles such as the hat and double hat section members, absorb the most of the energy during the front-end collision. The purpose of this study was to analyze the collapse characteristics of spot welded section members with respect to the pitch of spot welds on flanges, through impact experiments and computation for para-

The structure of a 20 Å thin Co layer embedded between Fe layers grown with molecular beam epitaxy on MgO is determined with ion beam channeling. From the position and the ratio of the widths of the angular yield profiles for different crystallographic directions, we show that Co is forced in the metastable body centered cubic structure.

We have ascertained the limits of reasonable application of the classical boundary element method for the solution of the antiplane problem of the theory of elasticity in the study of bodies with thin-walled elements of structure and geometry. We have proposed an approach for the regularization of singular and quasisingular integrals, which appear ...
