Journal ArticleDOI
Energy Gaps in Etched Graphene Nanoribbons
TL;DR: It is shown that two distinct voltage scales can be experimentally extracted that characterize the parameter region of suppressed conductance at low charge density in the ribbon.
Journal ArticleDOI
Ultrasensitive force detection with a nanotube mechanical resonator
Joel Moser,Johannes Güttinger,Alexander Eichler,Maria Jose Esplandiu,Dong E. Liu,Mark Dykman,Adrian Bachtold +6 more
TL;DR: Force sensing with nanotube resonators offers new opportunities for detecting and manipulating individual nuclear spins as well as for magnetometry measurements.
Journal ArticleDOI
Tunable Graphene Single Electron Transistor
TL;DR: Electronic transport experiments on a graphene single electron transistor are reported, investigating energy scales for the tunneling gap, the resonances in the constrictions, and for the Coulomb blockade resonances.
Journal ArticleDOI
Tunable Coulomb blockade in nanostructured graphene
TL;DR: In this paper, Coulomb blockade and Coulomb diamond measurements on an etched, tunable single-layer graphene quantum dot were performed and a charging energy of ≈3.5meV was obtained.
Journal ArticleDOI
Nanotube mechanical resonators with quality factors of up to 5 million
TL;DR: This work measures record-high quality factors Q as high as 5 × 10(6) in ultra-clean nanotube resonators at a cryostat temperature of 30 mK, comparable to the highest Q values reported in mechanical resonators of much larger size.
