TL;DR: In this paper, the authors employed Yb3+ and Er3+ ions doped in a narrow bandgap oxide Bi20TiO32:YbEr, which can achieve near-infrared (NIR) responsive upconversion (UC) photocatalysi...

TL;DR: Detailed investigations show that these versatile modulations of the SBH with the structure and strain are mainly attributed to the strong dependence of the band edges of TiO2 and the interfacial potential alignments on the strain and structure, suggesting that these results are general and may be applicable to other metal/TiO2 heterostructures.

TL;DR: In this article, bilayer graphene was used as the anode of a small molecule organic light-emitting diode (OLED) and the maxima of luminance efficiency and power efficiency reached 1.18cd A−1 and 0.41lm W−1, respectively.

TL;DR: The results show that Janus MXY monolayer has an intrinsic dipole moment and a direct band gap, however, for MXY bilayers strong interlayer coupling will cause direct to indirect band gap transition, and the existence of the dipole Moment leads to a significantly large interlayer band offset, being the driving force for the formation of interlayer excitons.

TL;DR: The results indicate that external strain can serve as an effective strategy for bandgap engineering, and the transition from semiconductor to metal occurs when a compressive strain of -8% is applied and the band edge positions of Sb/Bi in-plane heterostructures can meet the reduction potential of hydrogen generation in photocatalysis.
