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. ***

9803005任本基金支持以本科生为主的研究机构研究量子点中声子激发的各个方面。工作的重点是网点的降低维数的后果，包括界面和边缘模式和模式混合导致的约束。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。任将在一个以本科生为主的机构进行理论研究，旨在描述由相对较少数量的原子组成的原子尺度结构的原子振动，称为“量子点”。量子点在开发原子尺度的电子和光学器件方面具有潜在的用途。＊＊＊
