XAFS study of charge transfer in intercalation compounds
1997年12月2日 · It is then applied for an accurate characterization of the charge transfer in the case of lithium intercalation into TiS 2, from XAFS experiments at the sulfur K edge. It is concluded that sulfur atoms are largely taking part in the intercalation process.
Enhanced superconductivity in atomically thin TaS2 - Nature
2016年3月17日 · Only very recently, several studies of niobium diselenide (NbSe 2) flakes have yielded the first clear evidence of the existence of superconductivity in freshly cleaved specimens of less than three...
Charge density waves in 1T-TaS2: an EXAFS study - ScienceDirect
1998年7月15日 · Two polytypes (2H- and 1T-) of TaS 2 have been investigated by extended X-ray absorption fine structure (EXAFS) spectroscopy. The EXAFS data were in good agreement with the trigonal-prizmatic coordination of Ta in 2H-TaS 2. For 1T-TaS 2, a lattice distortion of Ta local surrounding was observed, attributed to charge density waves (CDW).
Charge transfer and spin-valley locking in 4Hb-TaS2 - Nature
2024年4月10日 · 4Hb-TaS 2 is a superconductor that exhibits unique characteristics such as time-reversal symmetry breaking, hidden magnetic memory, and topological edge modes. It is a naturally occurring...
Tunable superconductivity by electrochemical intercalation in TaS2 ...
2018年2月5日 · With this facile and efficient method, the superconducting transition temperature (Tc) of pristine TaS 2 increases from 0.8 K to the maximum 3.7 K, showing a dome-like behavior. The Hall coefficient measurement indicates that the intercalated CTA + cations introduce electrons to this system.
EXAFS studies of sodium intercalated 2H and 1T polytypes of TaS2
1995年3月1日 · Na intercalated 2H and 1T polytypes of TaS 2 have been studied by extended X-ray absorption fine-structure (EXAFS) experiments. The intercalated compounds were prepared by in situ evaporation of Na to the (0 0 0 1) cleaved surface of the TaS 2 crystal.
Abnormal Metal–Semiconductor-Like Transition and Exceptional …
2023年6月26日 · Here, we employ restacked TaS 2 ─a novel transition metal dichalcogenide (TMD) with weak vdW bonding and twisted angles─to investigate the strain effects of interlayer modulation on the electronic properties. Under pressure, an unexpected transition from metallic to semiconducting-like states occurs.
