项目摘要

Non-technical DescriptionThe demand for energy needed to store and process data is growing at an unsustainable rate. New technologies are clearly needed. Phase change materials, which can dramatically change their electronic, optical, and physical properties during phase transitions, offer a promising solution. Their tunability makes them promising candidates for emerging applications such as energy efficient in-memory computing. This FuSe project will explore a new class of phase change materials that combine five or more elements in comparable amounts. The field of materials science has been captivated by the discovery of such “high entropy” materials. For example, high entropy ceramics have unique thermal and mechanical properties not possible with simpler compositions. In this project, investigators will combine computational materials discovery with combinatorial synthesis to realize high entropy phase change materials. The most promising candidates will be characterized comprehensively and integrated into electronic and photonic computational devices. The team will establish a robust pipeline to educate the next-generation workforce. They will offer rotational internships so that students can work at different universities and in cross-cutting fields and promote their success through mentoring. The team will also create a partnership between the University of Maryland and Howard University, an HBCU, to promote the direct exchange of research mentorship and training.Technical DescriptionThe central hypothesis driving this Future of Semiconductors project is that high-entropy phase change materials (PCMs) can form a thermodynamically stable single phase when elements randomly occupy one type of lattice site and are present in high concentrations rather than as dopants. This structure, stabilized by large configurational entropy, will enable development of PCMS with low/zero resistance drift and large bandgaps (1.5 eV) or extinction coefficient contrast (∆k~2-3) for optical memristors in the visible and infrared. The proposed research comprises four thrust topics to be conducted in a closed-loop fashion. 1) First-principles computation material discovery to predict previously unexplored entropy-stabilized PCMs. 2) Combinatorial synthesis via sputtering of selenides and tellurides and thermal evaporation of sulfides in order to explore multiple compositions in a single run. 3) Electrical, optical, structural, and compositional material characterization to reveal the intrinsic (permittivity, structure, vibrational modes, composition, conductivity, capacitance, etc.) and extrinsic (void formations, capping, geometry, substrates) factors dictating device performance. 4) Integration of PCMs into photonic and electronic devices to demonstrate optical and electrical memristors and memcapacitors with optimal performance.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.
非技术描述存储和处理数据所需的能源需求正在以不可持续的速度增长。显然需要新技术。相变材料在相变过程中可以显著改变其电子、光学和物理特性,提供了一种有前途的解决方案。它们的可调性使它们成为新兴应用的有希望的候选者,例如节能内存计算。这个FuSe项目将探索一种新的相变材料,它将五种或五种以上的元素以可比的数量结合在一起。材料科学领域一直被这种“高熵”材料的发现所吸引。例如,高熵陶瓷具有独特的热性能和机械性能,这是更简单的组合物所不可能实现的。在这个项目中,研究人员将联合收割机计算材料发现与组合合成相结合,实现高熵相变材料。最有前途的候选人将被全面表征并集成到电子和光子计算设备中。该团队将建立一个强大的管道来教育下一代劳动力。他们将提供轮流实习,使学生可以在不同的大学和跨领域的工作,并通过指导促进他们的成功。该团队还将在马里兰州大学和霍华德大学之间建立伙伴关系,促进研究指导和培训的直接交流。技术描述驱动这个未来半导体项目的中心假设是,高熵相变材料(PCM)当元素随机占据一种类型的晶格位置并且以高浓度存在时,而不是掺杂剂。这种结构,通过大的构型熵来稳定,将使得能够开发具有低/零电阻漂移和大的带隙(1.5eV)或消光系数对比度(λ k~2-3)的用于可见光和红外线中的光学忆阻器的PCMS。拟议的研究包括四个重点专题,将以闭环方式进行。1)第一原理计算材料发现预测以前未探索的熵稳定PCM。2)通过溅射硒化物和碲化物以及热蒸发硫化物进行组合合成,以便在一次运行中探索多种组合物。3)材料的电学、光学、结构和成分表征,揭示其内在特性(介电常数、结构、振动模式、成分、电导率、电容等)以及决定器件性能的外在(空隙形成、封盖、几何形状、衬底)因素。4)将PCM集成到光子和电子器件中,以展示具有最佳性能的光电忆阻器和忆电容器。该奖项反映了NSF的法定使命,并通过使用基金会的知识价值和更广泛的影响审查标准进行评估,被认为值得支持。
