DOI: 10.1016/j.materresbull.2017.01.028
Abstract: Abstract Transition metal compounds with quasi-two-dimensional structure demonstrate a series of un-precedent quantum phases, such as topological insulator, topological phase transition under thermal/pressure stimuli, which is attributed to delicate interplay among interlayer coupling, spin-orbit coupling… read more here.

DOI: 10.1021/acs.chemmater.2c03283
Abstract: Despite the recent surge in interest in Cu3–xP for catalysis, batteries, and plasmonics, the electronic nature of Cu3–xP remains unclear. Some studies have shown evidence of semiconducting behavior, whereas others have argued that Cu3–xP is… read more here.

DOI: 10.1126/sciadv.adv0768
Abstract: The hot-carrier photothermoelectric (PTE) effect in two-dimensional materials can be used to develop room-temperature, fast, and sensitive detectors for microwave, terahertz, and far-infrared radiations. Here, we present a van der Waals semimetal PtSe2 terahertz detector… read more here.
