项目摘要
NON-TECHNICAL DESCRIPTION: With the exponential growth of information technologies, the ability to store huge amounts of data is becoming a major societal need. Phase-change materials are some of the most promising materials for future data-storage applications. They are the key component enabling high density optical data storage such as rewritable DVD (digital versatile disc) and nonvolatile computer memories (phase-change random access memory (PC-RAM)). However, they currently suffer from aging issues that lead to degradation over time and eventually to data loss. This research aims at developing a new generation of phase-change materials that are immune to this data-loss phenomenon. Moreover, such materials can enable emerging technologies (high density multilevel memories and ultrafast, artificial neuron-like processors) that rely on highly stable phase-change materials. Through the process of conducting this research, graduate students are being trained in the field of materials science and engineering. Materials expertise is in high demand in high technology sectors such as the microelectronic industry.TECHNICAL DETAILS: The discovery of phase-change materials exhibiting a pronounced fragile-to-strong transition is key to the development of memory devices that are immune to the data-loss phenomenon currently plaguing memory technologies. The discovery of these new materials is achieved by characterizing the thermodynamic and structural behavior of families of phase change materials. The goal is to identify materials that are immune to structural relaxation. These materials are key in enabling emerging technologies that rely on fractional changes in physical properties and are particularly sensitive to drift. This research therefore supports the development of transformational new technologies such as artificial neural-network processor for ultra-fast computing. From a fundamental point of view, this research provides key insight into the origin of fragile-to-strong transitions and answers outstanding related questions in glass science such as the origin of beta-relaxation and polyamorphism.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:随着信息技术的指数增长,存储大量数据的能力正在成为主要的社会需求。相变材料是未来数据存储应用中最有前途的材料之一。它们是实现高密度光学数据存储的关键部件,例如可编程数字多功能光盘(DVD)和非易失性计算机存储器(相变随机存取存储器(PC-RAM))。然而,它们目前存在老化问题,导致随着时间的推移而退化,最终导致数据丢失。这项研究的目的是开发新一代的相变材料,免疫这种数据丢失现象。此外,这种材料可以使依赖于高度稳定的相变材料的新兴技术(高密度多级存储器和超快人工神经元处理器)成为可能。通过进行这项研究的过程中,研究生正在材料科学和工程领域的培训。在高科技领域,如微电子行业,对材料专业知识的需求量很大。技术优势:相变材料的发现显示出明显的易碎到坚固的转变,这是开发不受当前存储技术中数据丢失现象影响的存储设备的关键。这些新材料的发现是通过表征相变材料家族的热力学和结构行为来实现的。目标是识别对结构松弛免疫的材料。这些材料是实现新兴技术的关键,这些技术依赖于物理特性的微小变化,对漂移特别敏感。因此,这项研究支持了变革性新技术的发展,例如用于超快速计算的人工神经网络处理器。从基础的角度来看,这项研究提供了从脆性到强性转变起源的关键见解,并回答了玻璃科学中悬而未决的相关问题,如β-弛豫和多晶的起源。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。
