CTS-9973845Sheryl EhrmanUniversity of Maryland, College ParkDiscrete quantities of materials (nanoclusters), whether separated by grain boundaries, or by gas or liquid molecules have very interesting and potentially very useful material properties which may differ significantly from those of their bulk counterparts. In this project, the growth of compound semiconductor nanoparticles from the gas-phase will be simulated assuming a collision/sintering mechanisms of particle growth. Results from this work will be important for the design of larger scale processes for nanoparticle synthesis, and, more fundamentally, for increasing our understanding of phenomena occurring during particle formation.This award is made in response to the POWRE solicitation.

CTS-9973845Sheryl Ehrman马里兰大学，学院公园离散数量的材料(纳米团)，无论是由晶界分隔，还是由气体或液体分子分隔，都具有非常有趣和潜在非常有用的材料特性，这些特性可能与它们的体相对应物显著不同。在本项目中，将假设颗粒生长的碰撞/烧结机制来模拟化合物半导体纳米颗粒从气相中的生长过程。这项工作的结果对于设计更大规模的纳米颗粒合成工艺将是重要的，更根本的是，有助于增加我们对颗粒形成过程中现象的理解。该奖项是应POWRE的邀请而颁发的。
