Transition metal tellurides (TMTs) have attracted intense interest due to their intriguing physical properties arising from their diverse phase topologies. To date, a wide range of physical properties have been discovered for TMTs, including that they can act as topological insulators, semiconductors, Weyl semimetals, and superconductors. Among the TMT families, MoTe2 is a representative material because of its Janus nature and rich phases. In this Perspective, we first introduce phase structures in monolayer and bulk MoTe2 and then summarize MoTe2 synthesis strategies. We highlight recent advances of Janus MoTe2 in terms of material structures and emerging quantum states. We also provide insight into the opportunities and challenges faced by MoTe2-associated device design and applications.

MoTe2:半导体还是半金属?

过渡金属碲化物 (TMTs) 因其多样化的相拓扑结构而产生有趣的物理性质而引起了人们的强烈兴趣。迄今为止,已发现 TMT 具有广泛的物理特性,包括它们可以充当拓扑绝缘体、半导体、外尔半金属和超导体。在 TMT 家族中,MoTe 2因其 Janus 性质和丰富的相而成为代表性材料。在这个视角中,我们首先介绍单层和块状 MoTe 2 的相结构,然后总结 MoTe 2合成策略。我们重点介绍 Janus MoTe 2 的最新进展在材料结构和新兴量子态方面。我们还深入了解 MoTe 2相关设备设计和应用所面临的机遇和挑战。
