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".

我们在此主要仪器提案中的总体目标是获得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，并具有多项重要优势：1．它是非侵入性的，因为探头本身是非磁性的。2。它直接测量磁场而不是场导数（如 MFM）。3．其低温灵敏度已与最好的微型 SQUID 兼容。4。它具有扫描功能（与微型 SQUID 相比），可以在大的外部磁场中运行。我们将与显微镜制造商 NanoMagnetics Instruments 合作，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，具有出色的到达能力。更广泛的影响这项工作如果成功，将为独特纳米结构的纳米制造奠定新的基础，并在分子智能表征和单电荷操纵方面具有潜在应用。 SHPM的收购和发展将使来自WSU多个不同院系（物理、化学、电气和计算机工程）的教师能够整合多学科研究和学生培训。为了补充研究项目，PI 和 Co-PI 将使用 SHPM 开发试点项目，在 WSU 引入高级研究项目作为课程的必修部分。该仪器还将有助于扩大本科生对当前 NSF 资助的 IGERT 和 REU 项目的参与，并且对于研究生跨学科课程“材料和表征技术”以及新的研究生课程“磁学、磁性器件和纳米技术”也是不可或缺的。
