2024年4月23日 · In this study, we present a unique approach to unlock the intertwined two-dimensional Mott-insulator and three-dimensional band-insulator states in bulk 1T-TaS2 crystals by structuring a...

2008年11月9日 · Here, we show the appearance of a series of low-temperature electronic states in 1T-TaS 2 with pressure: the Mott phase melts into a textured charge-density wave (CDW); superconductivity develops...

1993年7月1日 · Ultrathin films of TaS 2, a two-dimensional metal known for charge density waves (CDWs) and polytypes, have been grown epitaxially on various layered substrates by molecular beam epitaxy and characterized with surface science techniques. STM image of the films shows irregular modulation which has similarity with that of the CDW.

The high activity of the as-synthesized F-1T′ MoTe 2 /CC electrode for HER in 1 M H 2 SO 4 solution was demonstrated by the small onset overpotential of −230.7 mV, a low Tafel slope of 127.1 mV dec –1, and robust electrochemical durability.

1994年5月15日 · Our results demonstrate that the metallic NbSe2 effect on the semi-metallic MoS2 reduces the band gap of MoS2 up to 140 meV. Moreover, these heterostructures exhibit outstanding absorption...

2024年11月1日 · Chemical intercalation of Co into MoTe 2 induces phase transition and ferromagnetism. Enhanced conductivity in Co-MoTe 2 facilitates direct observation of ferromagnetism. Co-MoTe 2 exhibits 4 % magnetoresistance with hysteresis at room temperature. DFT calculations validate MR enhancement from inserted Co’s local magnetic moments.

2020年8月25日 · 1T-TaS2是一种具有丰富物相的层状二维材料。其在经过多个电荷密度波相变后，在低温下变为绝缘体。而这一现象的起因一直存疑。张焱课题组和合作者，从实验上对其电子结构和晶格结构进行了刻画，并揭示了其绝缘性的起因。

2024年7月25日 · 结果表明，与原始相相比，锂化相 II（或锂化相 I）的电阻显著（或适度）增加，霍尔载流子密度降低，表明在锂化相从半金属转变为半导体时，带隙打开。总的来说，这项工作在 1T′-MoTe2 中引入了两种之前未报道过的相，这些相是由 Li+ 插入引起的。

2017年4月17日 · 为探究二硫化钽中莫特绝缘相的起源，人工微结构科学与技术协同创新中心成员，复旦大学物理系张远波教授研究组及其合作者电压脉冲在莫特绝缘相中制造出一种热平衡下不存在的“马赛克”电荷密度波亚稳态。 借助扫描隧道显微镜的局域电子态密度测量，他们首次发现在这一亚稳相的区块中，层与层之间电荷密度波的堆叠关系不再固定。 而莫特绝缘相只出现在了少数几 …
