RUI: Microscopic Modeling of Phonon Modes in Semiconductor Quantum Dots

小行星9803005 该补助金支持在一个以本科为主的机构研究量子点中声子激发的各个方面。 这项工作的重点是减少维数的点，包括界面和边缘模式和模式混合所造成的限制的后果。PI将使用微观模型来计算量子点中的实际声子模式，并研究电子-声子耦合对载流子弛豫和光学性质的影响。 任正非将在一个以本科为主的机构进行理论研究，该机构寻求描述由相对少量的原子组成的原子尺度结构的原子振动，这些原子被称为“量子点”。量子点在开发原子级电子和光学器件方面具有潜在的用途。 ***

9803005 Ren This grant supports research at a predominantly undergraduate institution to study aspects of phonon excitations in quantum dots. The work focuses on consequences of the reduced dimensionality of the dot, including interface and edge modes and mode mixing resulting from confinement. The PI will use a microscopic model to calculate realistic phonon modes in quantum dots and to investigate the effect of electron-phonon coupling on carrier relaxation and optical properties. %%% Ren will carry out theoretical research at a predominantly undergraduate institution that seeks to describe the atomic vibrations of atomic-scale structures consisting of a relatively small number of atoms known as `quantum dots.' Quantum dots are potentially useful in developing atomic- scale electronic and optical devices. ***
