CAREER: Structural and Functional Mimics of Colloidal Quantum Dot Surfaces

通过这一奖项，化学系的高分子、超分子和纳米化学计划以及化学结构和动力学-B计划将资助马萨诸塞大学阿默斯特分校的Kevin Kittilstve教授开展基础研究，以更好地了解纳米半导体的性质。它们在发光设备和显示技术中具有潜在的实用价值。此外，Kittilstve教授正在与地区社区学院发展新的合作伙伴关系，并加强现有的教育计划，旨在提高STEM领域中代表性不足的少数族裔的保留率。这一职业奖将为来自斯普林菲尔德技术社区学院的代表不足的新兴STEM学者和参加Eureka的女性学生提供暑期研究机会！霍利奥克女孩公司的计划。这项研究的长期目标是彻底了解半导体纳米晶体表面缺陷是如何形成的。这一职业项目的重点是利用一系列光谱和分析技术，阐明杂质与锌和镉(硫化物)-苯并苯并三聚氰酸酯簇合物的金属离子交换反应的热力学和动力学。具体目标是：(1)确定定向替代化学缺陷对不同尺寸团簇的形成动力学和热力学的影响；(2)研究掺杂杂质的团簇和相关掺杂胶体半导体纳米晶的电子结构；(3)通过暑期研究机会和增加辅导、咨询和联网，扩大代表不足的少数群体在化学和STEM本科课程中的参与度并提高其保留率。

With this award, the Macromolecular, Supramolecular and Nanochemistry Program and the Chemical Structure and Dynamics-B Program of the Division of Chemistry are funding Prof. Kevin Kittilstved of the University of Massachusetts-Amherst to conduct fundamental research toward better understanding the properties of nanoscale semiconductors. These are potentially useful in light-emitting devices and display technologies. In addition, Prof. Kittilstved is developing new partnerships with regional community colleges and strengthening existing educational programs aiming at increasing the retention rates of underrepresented minorities in the STEM fields. This CAREER award will provide summer research opportunities for underrepresented rising STEM scholars from Springfield Technical Community College and female students who participate in the Eureka! Program of Girls Inc. of Holyoke. The long term goal of this research is to gain a thorough understanding of how defects form on the surfaces of semiconductor nanocrystals. This CAREER project focuses on elucidating the thermodynamics and kinetics of the metal ion exchange reactions of impurities into zinc and cadmium-(chalcogenide)-benzenechalcogenolate clusters using a range of spectroscopic and analytical techniques. The specific objectives are: (1) to determine the effect of targeted, substitutional chemical defects on the formation kinetics and thermodynamics of the clusters of varying sizes; (2) to study the electronic structure of impurity-doped clusters and related impurity-doped colloidal semiconductor nanocrystals; and (3) to broaden the participation and increase the retention rates of underrepresented minorities in the chemistry and STEM undergraduate curriculum through summer research opportunities, and increased mentoring, advising and networking.
