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".

我们在这个主要仪器提案的总体目标是获得一个独特的扫描霍尔探针显微镜（SHPM）。该仪器具有出色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。2.它直接测量磁场而不是磁场导数（如MFM）。3.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，并且（与微型SQUID相比）可以在大的外部磁场中工作。通过与显微镜制造商NanoMagnetics Instruments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，我们建议在量子点中测量单个自旋。这一阶段的实施将导致一个真正独特的仪器，具有出色的达到capabilities.Broader impactThis工作，如果成功的话，将建立新的基础，nanofabbands uniquenanostructures与潜在的应用在智能表征的分子和操纵的单电荷。SHPM的收购和发展将使来自WSU（物理，化学，电气和计算机工程）几个不同部门的教师能够整合多学科研究和学生培训。为了补充研究计划的PI和Co-PI将使用SHPM在一个试点计划的发展，介绍在WSU作为课程的必要部分的高级研究项目。该仪器还将有助于扩大目前NSF资助的IGERT和REU计划的本科生的参与，也将是研究生跨学科课程，材料和表征技术以及新的研究生课程“磁性，磁性器件和纳米技术”不可或缺的。
