Electrical control of neutral and charged excitons in a monolayer semiconductor.
TLDR
This work reports the unambiguous observation and electrostatic tunability of charging effects in positively charged, neutral and negatively charged excitons in field-effect transistors via photoluminescence and finds the charging energies for X(+) and X(-) to be nearly identical implying the same effective mass for electrons and holes.

Quantum supercurrent transistors in carbon nanotubes
TLDR
It is found, in good agreement with existing theory, that the product of the critical current and the normal state resistance becomes an oscillating function, in contrast to being constant as in previously explored regimes.
Gate-Controlled Superconducting Proximity Effect in Carbon Nanotubes.
TLDR
The superconducting proximity effect in single-walled carbon nanotubes connected to niobium electrodes was controlled with the use of nearby gates that tune the niobia-nanotube transparency with a dip in the low-bias differential resistance, indicating a proximity effect mediated by Andreev reflection.
Superconductivity in ropes of single-walled carbon nanotubes.
TLDR
Measurements on ropes of single-walled carbon nanotubes (SWNT) in low-resistance contact to nonsuperconducting metallic pads, at low voltage and at temperatures down to 70 mK strongly suggest the existence of superconductivity in ropes of SWNT.
