This is a Faculty Early Career Development (CAREER) Award, which investigates the mechanisms of nanocrystal assembly into electronic devices and the basic mechanisms of charge transport in them. The research will focus on the effects of Coulomb interactions, electron tunneling, and charge fluctuations. The model systems to be studied include well-defined configurations of nanocrystals in one and two-dimensional arrays. A range of tools will be used to study these systems, such as low-noise electrical measurements, charge imaging, and atomic-force microscopy. The project will provide excellent training for postdoctoral researchers, graduate and undergraduate students in device fabrication and measurements of nanostructures. As part of the proposed research, high-school students will be involved during the summer and will assist graduate students in the proposed experiments. As the electronic circuits are shrinking in size, the electronic industry will soon reach the nanometer size scales, where quantum effects dominate the electronic transport. At these small scales when electrons are confined into small regions, interesting new effects occur due to the fact that electronic charges and spins are quantized. The proposed research will focus on measurements of nanocrystals. Nanocrystals are nanometer-scale crystals that exhibit properties of both atoms and large crystals, and are already leading to new applications from electronics to biology and medicine. The proposed work will develop ways for controlled nanocrystal assembly into electronic devices, and will investigate the basic mechanisms of electronic transport through nanocrystal structures. This program is an excellent opportunity for undergraduate and graduate students to learn about device fabrication and electrical measurements. In addition, the female PI will be involved in a range of outreach activities, such as high-school outreach with the local Philadelphia schools, and the Women Interested in Studying Physics (WISP) group at the University of Pennsylvania.

这是一项教师早期职业发展（职业）奖，它调查了纳米晶体组装到电子设备中的机制以及其中的电荷运输的基本机制。该研究将重点介绍库仑相互作用，电子隧穿和电荷波动的影响。要研究的模型系统包括一个和二维阵列中纳米晶体的定义明确的配置。 一系列工具将用于研究这些系统，例如低噪声电测量，电荷成像和原子力显微镜。该项目将为博士后研究人员，研究生和本科生提供出色的培训。作为拟议研究的一部分，夏季将参与高中生，并将帮助研究生进行拟议的实验。随着电子电路的尺寸缩小，电子工业将很快到达纳米尺寸尺度，量子效应主导了电子传输。在这些小尺度上，当电子局限于小区域时，由于对电子电荷和旋转进行了量化，因此发生了有趣的新效果。 拟议的研究将集中于纳米晶体的测量。 纳米晶体是纳米尺度的晶体，它们都表现出既有原子和大晶体的特性，并且已经导致了从电子技术到生物学和医学的新应用。 拟议的工作将开发用于控制纳米晶体组装到电子设备中的方法，并将研究通过纳米晶体结构的电子传输的基本机制。该计划是本科生和研究生学习设备制造和电气测量结果的绝佳机会。 此外，女性PI将参与一系列外展活动，例如与当地费城学校的高中宣传以及有兴趣研究物理学的女性（WISP）小组（WISP）小组。
