(2011-08-25)While single crystalline materials such as Si dominate a myriad of applications, alloy materials like Si1-xGex are becoming increasingly attractive because of their enhanced material properties. Their intriguing material ...
Effect of phonon transport on the Seebeck coefficient and thermal conductivity of silicon nanowire arrays (2014-05-30)Thermoelectrics enable solid-state conversion of heat to electricity by the Seebeck effect, but must provide scalable and cost-effective technology for practical waste heat harvesting. This dissertation explores the ...
(2010-01-06)In this thesis, we explore the performance characteristics, speci cally the drain current drive, of the double gate silicon MOSFET device, using MoCa, the Monte Carlo simulator. Drain current performance is analyzed as a ...
(1973)The acoustic mismatch theory for the thermal boundary (Kapitza) resistance has peen modified so as to include the effect of phonon attenuation near the interface. The modified theory is in good agreement below 0.2 K with ...
(2012-05-22)Vibrational many-body methods for molecules and extended systems have been developed that can account for the effects of anharmonicity in the potential energy surfaces (PESs) on energies and other observable properties. For ...
