Healing away the dendrites The formation of lithium during charge-discharge cycles limits development metal batteries, because can cause electrical shorting cells. A number tricks have been used to try prevent dendrite formation. Li et al. took opposite approach (see Perspective by Mukhopadhyay and Jangid). They operated their cells at higher current densities, under which one would expect form owing nucleation rates. However, these conditions, that started heated up annealed, leading...
Spin and valley degrees of freedom in materials without inversion symmetry promise previously unknown device functionalities, such as spin-valleytronics. Control material with electric fields (ferroelectricity), while breaking additional symmetries, including mirror symmetry, could yield phenomena where chirality, spin, valley, crystal potential are strongly coupled. Here we report the synthesis a halide perovskite semiconductor that is simultaneously photoferroelectricity switchable chiral....
Abstract Crystallographic dislocation has been well-known to be one of the major causes responsible for unfavorable carrier dynamics in conventional semiconductor devices. Halide perovskite exhibited promising applications optoelectronic However, how impacts its ‘defects-tolerant’ halide is largely unknown. Here, via a remote epitaxy approach using polar substrates coated with graphene, we synthesize epitaxial controlled density. First-principle calculations and molecular-dynamics...
The reconfigurability of the electrical heterostructure featured with external variables, such as temperature, voltage, and strain, enabled electronic/optical phase transition in functional layers has great potential for future photonics, computing, adaptive circuits.

However, reconfigurable VO2-based associated devices are rare due to fundamental challenge integrating high-quality technologically...
As electronic devices shrink down to their ultimate limit, the fundamental understanding of interfacial thermal transport becomes essential in management. However, a comprehensive phonon mechanisms that drive is still under development. The across interfaces can be strongly affected by factors such as crystalline structure, surface roughness, chemical diffusion, etc. These complications lead significant quantitative uncertainty between experimentally measured boundary conductance (TBC) real...
