Effects of Disorder in Reduced Dimensional and Quantum Electronics

Weaver B.D., Aifer E.H., Naval Research Laboratory, US

We discuss the effect of atomic disorder on electronic systems that operate in either reduced dimension or by quantum-mechanical transport. Systems include high electron mobility transistors, tunnel diodes, superconductors, multiquantum well infrared and ultraviolet detectors, [...]

Growth of Copper on Ag(100) at Experimental Deposition Rates Using TAD

Sprague J., Montalenti F., Voter A.F., Naval Research Laboratory, US

The initial stages of growth of (001) Cu films on (001) Ag substrates have been investigated using the temperature accelerated dynamics (TAD) method. The acceleration provided by this method made it possible to simulate the [...]

Direct Write Technology as a Tool to Rapidly Prototype Patterns of Biological and Electronic Systems

Ringeisen B.R., Chrisey D.B., Piqué A., Krizman D., Brooks M., Spargo B., Naval Research Laboratory, US

The full potential of modeling and simulations is only realized when it is based on experimental results under varied conditions and systems. A single tool to rapidly prototype electronic and biological circuits would enhance the [...]

Scaling Issues for Calculations of Low-Velocity Gaseous Microflows

Kaplan C.R., Oran E.S., Naval Research Laboratory, US

Gaseous flows in microfluidic devices are often characterized by relatively high Knudsen numbers, Kn. For such flows, the continuum approximation is not valid, and Direct Simulation Monte Carlo (DSMC) is an appropriate solution method. However, [...]
