Journal ArticleDOI
Electrical, Thermal, and Mechanical Characterization of Silicon Microcantilever Heaters
Jungchul Lee,Thomas E. Beechem,Tanya L. Wright,Brent A. Nelson,Samuel Graham,William P. King +5 more
TL;DR: In this paper, the authors describe detailed mechanical, electrical, and thermal characterization and calibration of AFM cantilevers having integrated solid-state heaters, which have been applied to metrology, thermophysical property measurements, and nanoscale manufacturing.
Journal ArticleDOI
Direct-current triboelectricity generation by a sliding Schottky nanocontact on MoS 2 multilayers
Jun Liu,Ankur Goswami,Keren Jiang,Faheem Khan,Seokbeom Kim,Ryan McGee,Zhi Li,Zhiyu Hu,Jungchul Lee,Thomas Thundat,Thomas Thundat,Thomas Thundat +11 more
TL;DR: It is shown that continuous direct-current with a maximum density of 106 A m−2 can be directly generated by a sliding Schottky nanocontact without the application of an external voltage in efficient d.c. triboelectricity generation.
Journal ArticleDOI
Toward attogram mass measurements in solution with suspended nanochannel resonators.
TL;DR: Using suspended nanochannel resonators (SNRs), measurements of mass in solution with a resolution of 27 ag in a 1 kHz bandwidth are demonstrated, which represents a 100-fold improvement over existing suspended microchannel resonators and is the most precise mass measurement in liquid today.
Journal ArticleDOI
Weighing nanoparticles in solution at the attogram scale
Selim Olcum,Nathan Cermak,Steven C. Wasserman,Kathleen Christine,Hiroshi Atsumi,Kristofor R. Payer,Wenjiang Shen,Jungchul Lee,Angela M. Belcher,Sangeeta N. Bhatia,Scott R. Manalis +10 more
TL;DR: A nanomechanical resonator is developed that can directly measure the mass of individual nanoparticles down to 10 nm with single-attogram (10−18 g) precision, enabling access to previously difficult-to-characterize natural and synthetic nanoparticles.
Journal ArticleDOI
Sustained electron tunneling at unbiased metal-insulator-semiconductor triboelectric contacts
Jun Liu,Mengmeng Miao,Keren Jiang,Faheem Khan,Ankur Goswami,Ryan McGee,Zhi Li,Lan Nguyen,Zhiyu Hu,Jungchul Lee,Kenneth C. Cadien,Thomas Thundat,Thomas Thundat,Thomas Thundat +13 more
TL;DR: In this article, an unbiased, triboelectrically charged metal-insulator-semiconductor (MIS) point contact system, consisting of p-type silicon, silicon oxide and a metal tip, was proposed to produce sustainable tunneling current.
