TL;DR: The transmission electron microscope (TEM) is one of the most powerful techniques to obtain the microstructure of materials Equipped with energy dispersive X-ray (EDX) and electron energy loss spectroscopy (EELS), not only crystallographic structures but also chemical information at nano-scale, atomic scale and even sub-angstrom scale can be obtained as discussed by the authors.

TL;DR: In this research, the RFT of potential barriers and wells within a semiconductor multilayer is demonstrated to correlate with interfacial grading effect (IFG) and to affect the band offset strongly and the synergetic effect of RFT and IFG that serves as the first domino is shown to impact the subband structure and the electron transport successively.

TL;DR: A facile chemical transportation reaction for the synthesis of Ga2S3 microspheres with novel hollow morphologies and partially filled volumes is reported and novel guidelines toward the reasonable design of sulfide semiconductors with tunable photoluminescence properties are proposed.

TL;DR: A simple model based on modulus square of wave function (MSWF) is qualitatively built to shed new light on the relationship between QE and wave function overlap (WFO), finding that there exists a competition of WFO between the potential well regions and the interface regions, and a peak value of the overall WFO can be obtained under an appropriate voltage.
