Wearable sensor technologies are essential to the realization of personalized medicine through
continuously monitoring an individual’s state of health 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 …

A common feature of the single-walled carbon-nanotube field-effect transistors fabricated to
date has been the presence of a Schottky barrier at the nanotube–metal junctions 1 , 2 , 3 . …

The integration of materials having a high dielectric constant (high-κ) into carbon-nanotube
transistors promises to push the performance limit for molecular electronics. Here, high-κ (∼…

University in 2005 and was a Junior Fellow of the Harvard Society of Fellows from 2005 to 2006. …

Scaling of silicon (Si) transistors is predicted to fail below 5-nanometer (nm) gate lengths
because of severe short channel effects. As an alternative to Si, certain layered semiconductors …

We report high performance p-type field-effect transistors based on single layered (thickness,
∼0.7 nm) WSe 2 as the active channel with chemically doped source/drain contacts and …

Solar energy represents one of the most abundant and yet least harvested sources of
renewable energy. In recent years, tremendous progress has been made in developing …

Sweat potentially contains a wealth of physiologically relevant information, but has traditionally
been an underutilized resource for non-invasive health monitoring. Recent advances in …

Over the past several years, the inherent scaling limitations of silicon (Si) electron devices
have fuelled the exploration of alternative semiconductors, with high carrier mobility, to further …

Two-dimensional (2D) transition metal dichalcogenides have emerged as a promising
material system for optoelectronic applications, but their primary figure of merit, the room-…
