Two-dimensional MoS2 homojunctions, considered potential building blocks for next generation flexible electronics, currently suffer from quick degradation. Here, Zhang and co-workers use a self-healing sulfur vacancy mechanism to produce a MoS2 photodiode that possesses long term stability.
Two-dimensional transition metal dichalcogenides (TMDCs) exhibit attractive electronic and mechanical properties. In this Review, the charge density wave, superconductive and topological phases of TMCDs are discussed, along with their synthesis and applications in devices with enhanced mobility and with the use of strain engineering to improve their properties.
The first race involving molecular ‘cars’ stimulated technical advances in scanning tunnelling microscopy and provided insights in surface science and synthetic chemistry — it also attracted wide interest from the public.
A study on the formation of methylammonium lead iodide perovskite films reveals that light illumination influences the crystallization kinetics, therefore affecting the final photovoltaic performance of these materials.
