Anomalous Random Telegraphy Signal in Suspended Graphene with Oxygen Adsorption
Alexandro de Moraes Nogueira, Afsal Kareekunnan, Masashi Akabori +2
Graphene is a promising material for sensing applications because of its large specific surface area and low noise. In many applications, graphene will inevitably be in contact wit…
Berry curvature induced valley Hall effect in non-encapsulated hBN/Bilayer graphene heterostructure aligned with near-zero twist angle
Teppei Shintaku, Afsal Kareekunnan, Masashi Akabori +3
Valley Hall effect has been observed in asymmetric single-layer and bilayer graphene systems. In single-layer graphene systems, asymmetry is introduced by aligning graphene with he…
A Hysteresis Free Graphene Based Nanoelectromechanical Switch With Hexagonal Boron Nitride As A Contact
Jothiramalingam Kulothungan, Huynh Van Ngoc, Manoharan Muruganathan +1
Nano Electro Mechanical (NEM) contact switches have been widely studied as one of the alternative for classical field effect transistor (FET). An ideal NEM contact switch with hyst…
Vector Electrometry in a Wide-Gap Semiconductor Device Using a Spin Ensemble Quantum Sensor
Yang, Bang, Takuya Murooka +8
Nitrogen-vacancy (NV) centers in diamond work as a quantum electrometer. Using an ensemble state of NV centers, we propose vector electrometry and demonstrate measurements in a dia…
An In-situ Annealing effect of Graphene-Graphene Interlayer Conduction
Jothiramalingam Kulothungan, Manoharan Muruganathan, Hiroshi Mizuta
An interlayer distance modulation in twisted bilayer graphene is reported. This is achieved by an in-situ annealing technique. The transformation of systematic vacuum and hydrogen…
Stacking of nanocrystalline graphene for Nano-Electro-Mechanical (NEM) actuator applications
Kulothungan Jothiramalingam, Marek E. Schmidt, Muruganathan Manoharan +2
Graphene nano-electro-mechanical switches are promising components due to their excellent switching performance such as low pull-in voltage and low contact resistance. Mass fabrica…
