Nature：Steele 等人报道带隙超 7 eV 的半导体，将半导体推入绝缘体领域

Semiconductors pushed into insulator territory

AI 摘要

Steele 等人在 Nature 报告了一种带隙超过 7 eV 的半导体，创下已记录半导体带隙的最大值，将半导体推入长期由绝缘体占据的区间。该材料此前被认为属于电绝缘体，研究显示其实际为半导体，有望用于电子与光学器件。大带隙半导体适合高压、高温电子器件，但此类材料此前难以制备。 brief: yes

Semiconductors are materials that have an electrical conductivity between that of a conductor and an insulator. They are ubiquitous in modern technology, enabling the controlled flow of electricity in everything from solar cells to smartphones. The properties of a semiconductor are governed, in part, by its electronic bandgap — the energy needed to promote an electron to a conducting state. Semiconductors with large bandgaps are sought for electronic devices that must operate at high voltages or high temperatures, but such materials have been difficult to produce. Writing in Nature, Steele et al.1 report a semiconductor with the biggest bandgap recorded so far, which exceeds 7 electronvolts (eV). This demonstration pushes semiconductors into a regime that has long been reserved for insulators.
