Investigation of Band-Offsets at Monolayer-Multilayer MoS2 Junctions by Scanning Photocurrent Microscopy
Sarah L. Howell, Deep Jariwala, Chung-Chiang Wu +6
The thickness-dependent band structure of MoS2 implies that discontinuities in energy bands exist at the interface of monolayer (1L) and multilayer (ML) thin films. The characteris…
Gate-tunable carbon nanotube-MoS2 heterojunction p-n diode
Deep Jariwala, Vinod K. Sangwan, Chung-Chiang Wu +5
The p-n junction diode and field-effect transistor (FET) are the two most ubiquitous building blocks of modern electronics and optoelectronics. In recent years, the emergence of re…
Elucidating the photoresponse of ultrathin MoS2 field-effect transistors by scanning photocurrent microscopy
Chung-Chiang Wu, Deep Jariwala, Vinod K. Sangwan +3
The mechanisms underlying the intrinsic photoresponse of few-layer (FL) molybdenum disulphide (MoS2) field-effect transistors are investigated via scanning photocurrent microscopy.…
Extrinsic and Intrinsic Photoresponse in Monodisperse Carbon Nanotube Thin Film Transistors
Erik Sczygelski, Vinod K. Sangwan, Chung-Chiang Wu +5
Spectroscopic, time-resolved scanning photocurrent microscopy is shown to distinguish the intrinsic photoresponse of monodisperse semiconducting (99%) single-walled carbon nanotube…
Parametric amplification in single-walled carbon nanotube nanoelectromechanical resonators
Chung-Chiang Wu, Zhaohui Zhong
The low quality factor (Q) of Single-walled carbon nanotube (SWNT) resonators has limited their sensitivity in sensing application. To this end, we employ the technique of parametr…
A Fully Tunable Single-Walled Carbon Nanotube Diode
Chang-Hua Liu, Chung-Chiang Wu, Zhaohui Zhong
We demonstrate a fully tunable diode structure utilizing a fully suspended single-walled carbon nanotube (SWNT). The diode's turn-on voltage under forward bias can be continuously…
Capacitive Spring Softening in Single-Walled Carbon Nanotube Nanoelectromechanical Resonators
Chung Chiang Wu, Zhaohui Zhong
We report the capacitive spring softening effect observed in single-walled carbon nanotube (SWNT) nanoelectromechanical (NEM) resonators. The nanotube resonators adopt dual-gate co…
