TL;DR: Gold-assisted mechanical exfoliation of monolayer molybdenum disulfide, up to a centimeter scale, is demonstrated and electrochemical characterization reveals intriguing interactions between monolayers MoS2 and Au.

TL;DR: These findings provide an atomistic understanding of non-volatile switching and open a new direction in precision defect engineering, down to a single defect, towards achieving the smallest memristor for applications in ultra-dense memory, neuromorphic computing and radio-frequency communication systems.

TL;DR: In this paper, the specific vibrational and binding energy fingerprints of MoS2-Au interaction were identified using Raman and X-ray photoelectron spectroscopy, which indicate substantial strain and charge doping in monolayer MoS 2.

TL;DR: By engineering the complex reflectivity of a purpose-designed multilayer heterostructure composed of thin Au films (2-8 nm) on SiO2/Si substrate, the optical contrast of graphene and graphene oxide (GO) can be significantly enhanced in comparison to bulk Au, up to about 3 and 5 times, respectively.

TL;DR: By using an aperture stop to restrict the angle of incidence, high-magnification objectives can be made to achieve extraordinarily high optical contrast in a similar way as the low-m Magnification objectives, but still retaining the high spatial resolution capability.
