MRI: Acquisition of High Resolution Scanning Probe Hall Microscope

我们在这个主要仪器方案中的总体目标是获得一种独特的扫描霍尔探针显微镜(SHPM)。该仪器具有卓越的磁场成像和传感能力，并具有许多重要的优势：1.它是非侵入性的，因为探头本身是非磁性的。它直接测量磁场，而不是像在MFM中那样测量场导数。它在低温下的灵敏度已经与最好的微型SQUID兼容。它具有扫描能力，(与微型鱿鱼不同)可以在较大的外部磁场中工作。与显微镜制造商纳米磁性仪器公司合作，我们将进一步开发SHPM灵敏度，最终实现单电子自旋检测。特别是，我们建议对量子点中的单个自旋进行测量。这一阶段的实施将产生一种真正独特的仪器，具有出色的达到能力。布罗德影响这项工作如果成功，将为纳米制造独特的芳烃结构奠定新的基础，在分子的智能表征和单电荷的操纵方面具有潜在的应用前景。SHPM的收购和开发将使来自WSU(物理、化学、电气和计算机工程)几个不同系的教师能够整合多学科研究和学生培训。作为对研究方案的补充，私营部门和合作伙伴将利用SHPM制定一项试点方案，将西苏里州立大学的高级研究项目作为必修课程的一部分。该仪器还将帮助本科生更广泛地参与目前由NSF资助的IGERT和REU项目，并将在研究生跨学科课程、材料和表征技术以及新的研究生课程“磁性、磁性设备和纳米技术”中不可或缺。

Our overall objective in this Major Instrumentation proposal is to acquire a unique Scanning Hall Probe Microscope (SHPM). This instrument has exceptional magnetic field imaging and sensing capabilities and has a number of important advantages:1. It is non-invasive, as the probe itself is non-magnetic.2. It measures magnetic field directly rather than field derivatives (as in MFM).3. Its sensitivity at low temperatures is already compatible to the best micro-SQUIDs.4. It has scanning capabilities and (in contrast to a micro-SQUID) can operate in large external magnetic fields. In collaboration with the Microscope manufacturer, NanoMagnetics Instruments, we will further develop SHPM sensitivity, ultimately allowing single electron spin detection. In particular we propose to do measurements of a single spin in a quantum dot. The implementation of this stage will result in a truly unique instrument with outstanding reaching capabilities.Broader impactThis work, if successful, will establish the new basis for nanofabrication of uniquenanostructures with potential application in intelligent characterization of molecules and manipulation of single charges. The acquisition and development of SHPM will allow the faculty from several different departments at WSU (Physics, Chemistry, Electrical and Computer Engineering) to integrate the multidisciplinary research and student training. To compliment the research programs the PI and the Co-PIs will use SHPM in the development of a pilot program to introduce a Senior Research Project at WSU as a required part of the curriculum. The instrument will also help broaden the participation of undergraduate in the current NSF- funded IGERT and REU programs and will also be indispensable in the graduate interdisciplinary course, Materials and Characterization Techniques and of a new graduate course "Magnetism, Magnetic Devices and Nanotechnology".
