Title: Ultrafast lattice dynamics in lead selenide quantum dot induced by laser excitation

Abstract

We directly monitored the lattice dynamics in PbSe quantum dots induced by laser excitation using ultrafast electron di raction. The energy relaxation between the carriers and the lattice took place within 10 ps, showing no evidence of any signi cant phonon bottleneck e ect. Meanwhile, the lattice dilation exhibited some unusual features that could not be explained by the available mechanisms of photon- induced acoustic vibrations in semiconductors alone. The heat transport between the QDs and the substrate deviates signi cantly from Fourier's Law, which opens questions about the heat transfer under nonequilibrium conditions in nanoscale materials.

Comparison of multimesh hp-FEM to interpolation and projection methods for spatial coupling of reactor thermal and neutron diffusion calculations

Journal Article Dubcova, Lenka ; Solin, Pavel ; Hansen, Glen ; ... - Electrochimica Acta

Multiphysics solution challenges are legion within the ?eld of nuclear reactor design and analysis. One major issue concerns the coupling between heat and neutron ?ow (neutronics) within the reactor assembly. These phenomena are usually very tightly interdependent, as large amounts of heat are quickly produced with an increase in ?ssion events within the fuel, which raises the temperature that a?ects the neutron cross section of the fuel. Furthermore, there typically is a large diversity of time and spatial scales between mathematical models of heat and neutronics. Indeed, the di?erent spatial resolution requirements often lead to the use of very di?erentmore »« less
Development of SRF monolayer/multilayer thin film materials to increase the performance of SRF accelerating structures beyond bulk Nb

Thesis/Dissertation VALENTE-FELICIANO, Anne-Marie

The minimization of cost and energy consumption of future particle accelerators, both large and small, depends upon the development of new materials for the active surfaces of superconducting RF (SRF) accelerating structures. SRF properties are inherently a surface phenomenon as the RF only penetrates the London penetration depth ?, typically between 20 and 400 nm depending on the material. The greatest potential for dramatic new performance capabilities lies with methods and materials which deliberately produce the sub-micron-thick critical surface layer in a controlled way. Thus, two opportunities arise for the use of SRF thin ?lms as single layer superconductor ormore »« less

Dark Matter, the MCSSM and lattice QCD

Journal Article Joel Giedt, Anthony W. Thomas, and Ross D. Young - Physical Review Letters

Recent lattice measurements have given accurate estimates of the light and strange quark condensates in the proton. We use these new results to signi cantly improve the dark matter predictions in a set of benchmark models that represent di erent scenarios in the constrained minimal supersymmetric standard model (CMSSM). Because the predicted cross sections are at least an order of magnitude smaller than previously suggested, our results have signi cant consequences for dark matter searches.

Simulation of Non-resonant Internal Kink Mode with Toroidal Rotation in NSTX

Technical Report Fu, Guoyong

Plasmas in spherical and conventional tokamaks, with weakly reversed shear q pro le and minimum q above but close to unity, are susceptible to an non-resonant (m, n ) = (1, 1) internal kink mode. This mode can saturate and persist and can induce a (2; 1) seed island for Neoclassical Tearing Mode (NTMs)1 . The mode can also lead to large energetic particle transport and signi cant broadening of beam-driven current. Motivated by these important e ects, we have carried out extensive nonlinear simulations of the mode with nite toroidal rotation using parameters and pro les of an NTSXmore »« less

Engineering of Lead Selenide Quantum Dot Based Devices and Core/Shell Heterostructures

Thesis/Dissertation Nakotte, Tom

Near infrared (NIR) emitting colloidal quantum dots (QDs) such as PbSe are interesting materials for implementation in various optoelectronic devices such as solar cells, photodetectors, and radiation detectors. Material properties like size tunable emission wavelengths, facile solution processability, the possibility of carrier multiplication and Auger assisted up-conversion, and high Z number provide PbSe QDs with unique advantages over many currently available commercial materials used in these devices. In this dissertation, after an introduction to QDs in general, we first focus on synthesis of PbSe-based heterostructured QDs for study via optical spectroscopy. PbSe/CdSe QDs synthesized via cation exchange reaction were usedmore »« less
