Rate Equations For The Phonon Peak In Resonant-Tunneling Structures, Roger Lake, Gerhard Klimeck, J. P. Anantram, Supriyo Datta Nov 1993

Rate Equations For The Phonon Peak In Resonant-Tunneling Structures, Roger Lake, Gerhard Klimeck, J. P. Anantram, Supriyo Datta

Birck and NCN Publications

The ratio of the phonon peak current to the main peak current in double-barrier resonant-tunneling structures is significantly enhanced by barrier asymmetry. Previously, using the Keldysh formalism, we derived analytical expressions, valid in the zero-temperature, high-bias regime, which explained this eftect. We now provide analytical expressions valid for finite temperature and bias obtained from (i) an intuitive derivation using a rate equation approach and (ii) a more general derivation using the Keldysh formalism. The results of the two difFerent approaches are shown to be essentially identical for the ex- perimental device parameters. The finite temperature expressions shed light on the …

An Efficient Method For Computing Volume And Surface Area Over Grid Sampled Surfaces, June Ho Yi, David M. Chelberg Sep 1993

An Efficient Method For Computing Volume And Surface Area Over Grid Sampled Surfaces, June Ho Yi, David M. Chelberg

Department of Electrical and Computer Engineering Technical Reports

In this paper, we propose the volume between two surfaces normalized by the surface area as an invariant quantitative measure for comparing surface reconstruction results. The invariant property of the volume quantity provides the same measure with respect to an arbitrary coordinate system. By normalizing the volume by the surface area, the values of the measure can be compared for different size of images. We also present a computationally simple and efficient way of computing the volume between two surfaces and the surface area using a least-square-error fit plane approximation of a surface patch defined over a rectangular grid. Experiments …

A Tighter Lower Bound For 1-D Bin-Packing, Heng-Yi Chao, Mary P. Harper,, Russell Quong Jul 1993

A Tighter Lower Bound For 1-D Bin-Packing, Heng-Yi Chao, Mary P. Harper,, Russell Quong

Department of Electrical and Computer Engineering Technical Reports

For NP-complete problems, it may not be possible to find an optimal solution in polynomial time. However, efficient approximation algorithms for many NP-complete problems do exist. A good approach is to find tighter upper and lower bounds on the optimal solutions. As the gap between these two bounds approaches zero, optimality is reached. For minimization problems, any feasible solution serves as an upper bound. In general, researchers attempt to find heuristic algorithms to narrow the gap by decreasing the upper bound. Another approach is to narrow the gap by increasing the lower bound. To determine a good lower bound on …
