TL;DR: The photovoltaic properties of hybrid organic-inorganic perovskites are sensitive to the local microstructure, but difficult to quantify at the nanoscale as mentioned in this paper.

TL;DR: In this article, a scanning tunnelling microscopy study demonstrates that one-dimensional charge density waves can form at twin boundaries in a monolayer transition metal dichalcogenide.

TL;DR: This work reveals the enormous potential of employing oxide membranes to create and enhance ferroelectricity in environmentally benign lead-free oxides, which hold great promise for applications ranging from non-volatile memories and microwave electronics.

TL;DR: In this article, the authors observe and explore dynamic strain-induced ferroelectricity by laminating freestanding oxide films onto a stretchable polymer substrate using a combination of scanning probe microscopy, optical second harmonic generation measurements, and atomistic modeling.

TL;DR: In this article, the authors correlate different fabrication processes, optical spectroscopy and electron microscopy to identify the optical signatures of chalcogen vacancies in monolayer MoS2.
