Time-dependent electronic transport is increasingly important to the state-of-the-art device design and fabrication. The development of nanoscale sensing, the harnessing and control of structural fluctuations, and the advancement of next-generation materials all require a treatment of quantum dynamics beyond the level of traditional methods and a more nuanced approach to...
Electron transport and relaxation may be substantially different in low-dimensional
systems compared to that observed in bulk material. In the present work, Monte Carlo
models are used for the solution to the Boltzmann transport equation, with scattering
rates calculated quantum mechanically for superlattice and quantum wells. Carrier
relaxation following optical...
Decline in cardiac pump function is a hallmark of aging where mitochondrial decay is an important underlying cause. Although certainly multifactorial in nature, both dysfunction of the machinery involved in the chemiosmotic process of energy transduction and lower capacity to maintain fatty acid-driven respiration are identified as intrinsic factors of...
