EAGER: SUPER: Search for high-temperature superconductivity in heterostructured two-dimensional organic materials

非技术摘要：该项目的目标是设计和制造单层和多层有机材料，这些材料可以在室温和环境压力下具有超导性。显然，这一发现将是所有技术的革命，特别是在微电子学和能源转移和发电方面。但是，即使这一宏伟目标没有实现，具有编程功能的多层有机材料生长协议的开发也可以在半导体和可再生能源行业，光学和激光中应用。在教育方面，该项目为PI的团队带来了一个与有机化学相关的全新研究领域。通过小组会议和直接参与研究，研究生和本科生拓宽了他们在有机和量子化学方面的知识和专业知识，这些领域通常不是物理教育的一部分。该项目支持对本科生进行有机化学、半导体加工和运输、磁性和光学测量方面的培训。它还为本科生在夏季的研究创造了机会，提供给化学系的学生，从而使他们接触到物理实验室的许多方面。这种参与使学生为未来在工业和学术环境中的多学科合作工作做好了准备。技术摘要：该研究团队使用最先进的有机分子束外延（OMLE）方法制备了几系列有望在高温下具有超导性能的有机异质结构材料。OMLE允许构建标准方法无法实现的独特分子层内和层间排列。它们包括自组装单层和多层，由芳族分子如picene，chrysophosphate，NTCDI和场效应晶体管配置中的锚定富勒烯制成，其允许通过调节栅极电位来注入载流子。将具有施主和受主性质的分子混合以模拟电荷转移有机超导体中的分子排列。 PI实验室通过1.5-300 K范围内的输运和磁性测量来表征材料的物理性质。材料的生长通过原位椭圆偏振光谱法监测。电荷状态，电子能带形成，电荷转移和光学性质的研究使用犹他州大学共享的设施：X射线光电子能谱，光学吸收，和拉曼spectroscopy.This奖项反映了NSF的法定使命，并已被认为是值得的支持，通过使用基金会的智力价值和更广泛的影响审查标准进行评估。

Nontechnical Abstract:The project sets the goal to design and fabricate single- and multi-layer organic materials which can host superconductivity, potentially at room temperature and ambient pressure. Obviously, this discovery would be a revolution across all technologies but in particular in microelectronics and energy transfer and generation. But even if this grand goal is not achieved, the development of the protocols for growth of multilayered organic materials with programmed functionality enables applications in semiconductor and renewable energy industries, optics and lasing. On the educational side, the project brings into the PI’s group an entirely new area of research linked to organic chemistry. Through group meetings and direct participation in the research, graduate and undergraduate students broaden their knowledge and expertise in organic and quantum chemistry, fields that are typically not part of physics education. The project supports training of undergraduate students in organic chemistry, semiconductor processing and transport, magnetic and optical measurements. It also creates opportunities for undergraduate research during summer, to be offered to the students from Department of Chemistry, thus exposing them to many aspects of physics lab. This engagement makes students ready for future collaborative multi-disciplinary work in industrial and academic environment.Technical Abstract: The research team uses the state-of-the-art method of organic molecular beam epitaxy (OMLE) to fabricate several series of organic heterostructured materials anticipated to have superconducting properties at high temperatures. OMLE allows to construct unique molecular intra-layer and inter-layer arrangements inaccessible by standard methods. They include self-assembled monolayers and multilayers made from aromatic molecules such as picene, chrysene, NTCDI, and anchored fullerenes in the configuration of field-effect transistor, which allows to inject carriers by adjusting the gate potential. Molecules with donor and acceptor properties are mixed to imitate molecular arrangements in charge-transfer organic superconductors. The physical properties of materials are characterized by transport and magnetic measurements in the range 1.5-300 K in the PI’s lab. The growth of the materials is monitored by in-situ spectroscopic ellipsometry. The charge states, electronic band formation, charge-transfer and optical properties are studied using University of Utah shared facilities: x-ray photoelectron spectroscopy, optical absorption, and Raman spectroscopies.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
