TL;DR: In this paper, the authors reported reduced contact resistance of single-layer graphene devices by using ultraviolet ozone treatment to modify the metal/graphene contact interface, which was fabricated from mechanically transferred, chemical vapor deposition grown single layer graphene.
Journal ArticleDOI
Flexible light-emitting devices based on chirality-sorted semiconducting carbon nanotube films.
TL;DR: It is demonstrated that chirality-sorted CNTs have large advantages in transparent and flexible infrared light source applications and the electric properties and electroluminescence spectra of devices do not decay apparently.
Journal ArticleDOI
Electroluminescence from serpentine carbon nanotube based light-emitting diodes on quartz.
TL;DR: A light-emitting diode is fabricated and characterized on a semiconducting serpentine CNT which has many parallel segments with identical chirality, which shows improvement of an order of magnitude in current, significantly larger electroluminescent intensity, and narrower emission bands.
Journal ArticleDOI
Direct observation of substrate induced exciton in carbon nanotube
TL;DR: In this paper, the electroluminescence spectra of a single-walled carbon nanotube (CNT) grown to serpentine shape on quartz substrate was measured.
