Landauer's formula with finite-time relaxation: Kramers' crossover in electronic transport

Creator:: Gruss, Daniel, Velizhanin, Kirill A., and Zwolak, Michael
Abstract:: Landauer’s formula is the standard theoretical tool to examine ballistic transport in nano- and meso-scale junctions, but it necessitates that any variation of the junction with time must be slow compared to characteristic times of the system, e.g., the relaxation time of local excitations. Transport through structurally dynamic junctions is,...

Tunable thermal switching via DNA-based nano-devices

Creator:: Chien, Chih-Chun, Velizhanin, Kirill A., Dubi, Yonatan, and Zwolak, Michael
Abstract:: DNA has a well-defined structural transition-the denaturation of its double-stranded form into two single strands-that strongly affects its thermal transport properties. We show that, according to a widely implemented model for DNA denaturation, one can engineer DNA 'heattronic' devices that have a rapidly increasing thermal conductance over a narrow temperature...

Crossover behavior of the thermal conductance and Kramers' transition rate theory

Creator:: Velizhanin, Kirill A., Sahu, Subin, Chien, Chih-Chun, Dubi, Yonatan, and Zwolak, Michael
Abstract:: Kramers’ theory frames chemical reaction rates in solution as reactants overcoming a barrier in the presence of friction and noise. For weak coupling to the solution, the reaction rate is limited by the rate at which the solution can restore equilibrium after a subset of reactants have surmounted the barrier...

Anadromy and residency in steelhead and rainbow trout (Oncorhynchus mykiss): a review of the processes and patterns

Creator:: Kendall, Neala W., McMillan, John R., Sloat, Matthew R., Buehrens, Thomas W., Quinn, Thomas P., Pess, George R., Kuzishchin, Kirill V., McClure, Michelle M., and Zabela, Richard W.
Abstract:: Oncorhynchus mykiss form partially migratory populations with anadromous fish that undergo marine migrations and residents that complete their life cycle in fresh water. Many populations’ anadromous components are threatened or endangered, prompting interest in understanding ecological and evolutionary processes underlying anadromy and residency. In this paper, we synthesize information to...

Extremely efficient photocurrent generation in carbon nanotube photodiodes enabled by a strong axial electric field

Creator:: McCulley, Daniel R., Senger, Mitchell J., Bertoni, Andrea, and Perebeinos., Vasili
Abstract:: Carbon nanotube (CNT) photodiodes have potential to convert light into electrical current with high efficiency. However, previous experiments have revealed photocurrent quantum yield (PCQY) well below 100%. In this work, we show that axial electric field increases the PCQY of CNT photodiodes. In optimal conditions our data suggest PCQY >...

A Genetic Algorithm Approach to Imaging the Internal Southern San Andreas Fault Zone

Creator:: Reinhard, Hannah R.
Abstract:: The southern San Andreas fault (SSAF) is the fault segment with the highest 30-year probability of causing a moderate to large magnitude earthquake in California, yet key structural characteristics of the fault remain unconstrained, particularly in the Coachella Valley where the fault splits into the Banning (BF) and Mission Creek...

Quantum and Classical Simulation of Electronic Transport at the Nanoscale

Creator:: Gruss, Daniel S.
Abstract:: 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...

Controlling the Co-Precipitation of Colloidal PbSe Quantum Dots and Their Device Performance in a Diode Architecture

Creator:: McCrea, Tyler D.
Abstract:: In this work, colloidal PbSe quantum dots (QDs) are shown to be synthesized in a controlled manner by changing the growth time and reaction temperature in a microwave synthesis method. It is explained why quantum dots make such a unique material to create electronic devices and the specific benefits that...
