DOI: 10.1002/adfm.201905056
Abstract: Fabricating single‐crystalline gallium nitride (GaN)‐based devices on a Si(100) substrate, which is compatible with the mainstream complementary metal‐oxide‐semiconductor circuits, is a prerequisite for next‐generation high‐performance electronics and optoelectronics. However, the direct epitaxy of single‐crystalline GaN… read more here.

DOI: 10.1002/adfm.202003631
Abstract: Deterministic patterning of inorganic semiconducting micro‐/nanostructures has laid the foundation for the on‐chip integration of optoelectronic devices. However, it requires complicated equipment for thin‐film deposition, lithography, and etching. Solution‐processing bottom‐up integration of micro‐/nanostructures has been… read more here.

DOI: 10.1002/adfm.202005956
Abstract: Silicon has attracted considerable interest as a high‐capacity anode material for next‐generation lithium‐ion batteries. However, Si‐based anodes suffer extreme volume change (≈380%) upon lithiation and delithiation, which results in rapid capacity fading due to mechanical… read more here.
