Highly scalable, wearable surface-enhanced Raman spectroscopy
Limei Liu, Pablo Martinez Pancorbo, Ting-Hui Xiao +10
The last two decades have witnessed a dramatic growth of wearable sensor technology, mainly represented by flexible, stretchable, on-skin electronic sensors that provide rich infor…
Tuning of temperature dependence of resonance frequency shift of atomically thin mechanical resonators with van der Waals heterojunction
Taichi Inoue, Yuta Mochizuki, Kuniharu Takei +2
Atomically thin 2-dimensional (2D) mechanical resonators are expected to be highly sensitive force sensor and high performance nano-electro-mechanical systems because of their exce…
Resonance control of graphene drum resonator in nonlinear regime by standing wave of light
Taichi Inoue, Yuki Anno, Yuki Imakita +3
We demonstrate the control of resonance characteristics of a drum type graphene mechanical resonator in nonlinear oscillation regime by the photothermal effect, which is induced by…
High Performance Single Layered WSe2 p-FETs with Chemically Doped Contacts
Hui Fang, Steven Chuang, Ting Chia Chang +3
We report high performance p-type field-effect transistors based on single layered (thickness, ~0.7 nm) WSe2 as the active channel with chemically doped source/drain contacts and h…
Highly Quantum-Confined InAs Nanoscale Membranes
Kuniharu Takei, Hui Fang, Bala Kumar +10
Nanoscale size-effects drastically alter the fundamental properties of semiconductors. Here, we investigate the dominant role of quantum confinement in the field-effect device prop…
Ultrathin compound semiconductor on insulator layers for high performance nanoscale transistors
Hyunhyub Ko, Kuniharu Takei, Rehan Kapadia +13
Over the past several years, the inherent scaling limitations of electron devices have fueled the exploration of high carrier mobility semiconductors as a Si replacement to further…
Dramatic reduction of surface recombination by in-situ surface passivation of silicon nanowires
Yaping Dan, Kwanyong Seo, Kuniharu Takei +3
Nanowires have unique optical properties [1-4] and are considered as important building blocks for energy harvesting applications such as solar cells. [2, 5-8] However, due to thei…
Development of a Compact Neutron Source based on Field Ionization Processes
Arun Persaud, Ian Allen, Michael R. Dickinson +4
The authors report on the use of carbon nanofiber nanoemitters to ionize deuterium atoms for the generation of neutrons in a deuterium-deuterium reaction in a preloaded target. Acc…
