The rise of 2D non-layered materials in optoelectronics

Mon, 03/05/2018 - 07:41
For the first time, liquid-phase exfoliation (LPE) - a widely explored technique to obtain two-dimensional (2D) layered nano-architectures - has been successfully used to exfoliate tellurium, a non-layered material. The resulting 2D Te nanosheets exhibit excellent photoresponse behavior from the UV to the visible regime in association with strong time and cycle stability for on/off switching behavior. This intriguing finding could help in the search for other 2D materials for innovative applications.

Fluorinated phosphorene: a new way of solving instability problems in phosphorene

Fri, 03/02/2018 - 08:44
Recently, a new member has been introduced to the family of two-dimensional (2D) materials: phosphorene. Phosphorene has attracted much attention because of its tunable direct band gap and superior carrier mobility, but unfortunately phosphorene is subjected to oxidation and degradation under ambient conditions. Now, researchers have reported a facile pathway in obtaining and stabilizing phosphorene through a one-step, ionic liquid-assisted electrochemical exfoliation and synchronous fluorination process. This strategy enabled a novel phosphorene derivative to be discovered - fluorinated phosphorene, which exhibits air-stable photo-thermal properties.
