ABSTRACT:Proposal No: 0508346Title: MICROSCOPIC TRAPS FOR ELECTRONS IN VACUUM PI: Marija DrindicInst: University of Pennsylvania The objective of this NSF NER proposal is to build the first microscopic traps for cold (low-energy) electrons in vacuum and to demonstrate the trapping, detection, and manipulation of single electrons at small scales above surfaces in vacuum. The intellectual merit of this proposal is in developing the technologies for electron trapping, detection and manipulation on small scales in vacuum. In realizing these traps, it will be studied how the electrons interact with nearby surfaces at nanometer and micrometer length-scales, and how the electron motion can be detected and controlled near microfabricated wires. The broad impact of the proposed research is that it will present the first realization of electron "quantum dots" or "artificial atoms" in vacuum. An electron in a microtrap resembles a hydrogen atom; the hydrogen nucleus will be "replaced" in the proposed case by the electrodes of the microtrap. Control of electrons on microscopic scales is expected to open up new possibilities at the interface of atomic and condensed matter physics including integrated electronic circuits in vacuum, single and coupled quantum dots in vacuum and possible implementation of quantum computers. The PI is actively supporting the research of undergraduates, and one undergraduate will be involved in the proposed exploratory project.

摘要：提案编号：0508346标题：真空中电子的微观陷阱PI：Marija DrdinInst：宾夕法尼亚大学这项NSF NER提案的目标是建立第一个真空中冷(低能)电子的微观陷阱，并演示在真空中表面上方小尺度上的单电子的陷阱、探测和操纵。这一提议的智力价值在于开发了在真空中进行小范围电子捕获、探测和操纵的技术。在实现这些陷阱的过程中，将研究电子如何在纳米和微米长度尺度上与附近的表面相互作用，以及如何在微细加工导线附近检测和控制电子运动。这项拟议研究的广泛影响是，它将首次在真空中实现电子“量子点”或“人造原子”。微陷阱中的电子类似于氢原子；在所提出的情况下，氢核将被微陷阱的电极“取代”。电子在微观尺度上的控制有望在原子和凝聚态物理的界面上开辟新的可能性，包括真空中的集成电路，真空中的单个和耦合量子点，以及可能的量子计算机的实现。PI正在积极支持本科生的研究，一名本科生将参与拟议的探索性项目。
