2D semiconductors such as transition metal dichalcogenides (TMDs) and black phosphorus
(BP) are currently attracting great attention due to their intrinsic bandgaps and strong …

It has been a long-standing challenge to produce air-stable few- or monolayer samples of
phosphorene because thin phosphorene films degrade rapidly in ambient conditions. Here we …

Wearable devices are drawing increasing attention in both academia and industry in that
they can offer unprecedented information related to human health in real-time and human–…

This paper presents a review on our recent work on carbon nanotube field effect transistors,
including the development of ohmic contacts, high-κ gate dielectric integration, chemical …

Phosphorene is a new family member of two-dimensional materials. We observed strong
and highly layer-dependent photoluminescence in few-layer phosphorene (two to five layers). …

Metallic and semiconducting carbon nanotubes generally coexist in as-grown materials. We
present a gas-phase plasma hydrocarbonation reaction to selectively etch and gasify …

Hybrid organic–inorganic perovskite materials have received substantial research attention
due to their impressively high performance in photovoltaic devices. As one of the oldest …

Monolayer phosphorene provides a unique two-dimensional (2D) platform to investigate the
fundamental dynamics of excitons and trions (charged excitons) in reduced dimensions. …

Crystalline porous metal–organic frameworks (MOFs) with nanometer‐sized void spaces,
large surface areas and ordered reticular motifs have offered a platform for achieving …

Nanostructured silicon thin film solar cells are promising, due to the strongly enhanced light
trapping, high carrier collection efficiency, and potential low cost. Ordered nanostructure …
