With the miniaturization of crystals-based photoelectric devices, electrode contact-geometries may play a critical role in determining device performance. However, investigation contact geometries situ faces great challenges due to geometry is typically unmodifiable. To this end, kind liquid metal employed as an adaptive-deformable study carrier transport through perovskite microcrystals, which...

Abstract Among the family of transition metal dichalcogenides, 1T-TaS 2 stands out for several peculiar physical properties including a rich charge density wave phase diagram, quantum spin liquid candidacy and low temperature Mott insulator phase. As is thinned down to few-layer limit, interesting physics emerges in this quasi 2D material. Here, using scanning near-field optical microscopy, we ...
