Atomic-Level Understanding toward a High-Capacity and High-Power Silicon Oxide (SiO) Material

, 2016
Silicon oxide (SiO) has attracted much attention as a promising anode material for Li-ion batteries. The lithiation of SiO results in the formation of active Li–Si alloy cores embedded in an inactive matrix consisting of Li-silicates (Li2Si2O5, Li6Si2O7,

Solar-energy conversion and light emission in an atomic monolayer p-n diode.

Nature Nanotechnology, 2013
The limitations of the bulk semiconductors currently used in electronic devices-rigidity, heavy weight and high costs--have recently shifted the research efforts to two-dimensional atomic crystals such as graphene and atomically thin transition-metal ...

Tunable isolated attosecond X-ray pulses with gigawatt peak power from a free-electron laser

Nature Photonics, 2019
The quantum-mechanical motion of electrons in molecules and solids occurs on the sub-femtosecond timescale. Consequently, the study of ultrafast electronic phenomena requires the generation of laser pulses shorter than 1 fs and of sufficient intensity to
