电子辐照对层状量子材料的影响

Effect of electron-irradiation on layered quantum materials

Ajit Kumar Dash, Mainak Mondal, Manvi Verma, Keerthana S Kumar, Akshay Singh

摘要:

迈向量子时代的技术进步需要安全通信、量子计算和超灵敏传感能力。层状量子材料(LQM)具有显著的光电和量子特性,可以将我们带入量子时代。电子显微镜是在原子和纳米尺度上测量这些LQM的首选工具。另一方面,LQM的电子辐照可以改变各种材料特性,包括结构缺陷的产生。我们回顾不同类型的结构缺陷,以及电子弹性和非弹性散射诱导的过程。控制修改的光电和量子特性的LQM使用电子辐照,包括创建单光子发射器进行了讨论。鼓励通过其他层状材料封装来保护电子辐照引起的LQM损伤。我们最后给出了挑战和机遇的见解,包括使用电子束创建新的结构。

英文摘要:

Technological advancement towards the quantum era requires secure communication, quantum computation, and ultra-sensitive sensing capabilities. Layered quantum materials (LQMs) have remarkable optoelectronic and quantum properties that can usher us into the quantum era. Electron microscopy is the tool of choice for measuring these LQMs at an atomic and nanometer scale. On the other hand, electron-irradiation of LQMs can modify various material properties, including the creation of structural defects. We review different types of structural defects, as well as electron elastic- and inelastic-scattering induced processes. Controlled modification of optoelectronic and quantum properties of LQMs using electron-irradiation, including creation of single photon emitters is discussed. Protection of electron-irradiation induced damage of LQMs via encapsulation by other layered materials is encouraged. We finally give insights into challenges and opportunities, including creating novel structures using an electron beam.
