Tunneling photo-thermoelectric effect in monolayer graphene/bilayer hexagonal boron nitride/bilayer graphene asymmetric van der Waals tunnel junctions
Sabin Park, Rai Moriya, Yijin Zhang +3
Graphene is known to exhibit a pronounced photo-thermoelectric effect (PTE) in its in-plane carrier transport and attracting attention toward various optoelectronic applications. I…
Selective Etching of Hexagonal Boron Nitride by High-Pressure CF4 Plasma for Individual One-dimensional Ohmic Contacts to Graphene Layers
Yuta Seo, Satoru Masubuchi, Eisuke Watanabe +5
We describe a technique for making one-dimensional ohmic contacts to individual graphene layers encapsulated in hexagonal boron nitride (h-BN) using CF4 and O2 plasmas. The high et…
Detection of cyclotron resonance using photo-induced thermionic emission at graphene/MoS2 van der Waals interface
Yusai Wakafuji, Rai Moriya, Sabin Park +5
We demonstrate the detection of cyclotron resonance in graphene by using a photo-induced thermionic emission mechanism at the graphene/MoS2 van der Waals (vdW) Schottky junction. A…
Photo-Nernst detection of cyclotron resonance in partially irradiated graphene
Kei Kinoshita, Rai Moriya, Satoru Masubuchi +3
Cyclotron resonance of a Landau-quantized graphene can absorb significant amount of infrared light. However, application of this phenomenon to the photodetector had been limited du…
Dry release transfer of graphene and few-layer h-BN by utilizing thermoplasticity of polypropylene carbonate for fabricating edge-contact-free van der Waals heterostructures
Kei Kinoshita, Rai Moriya, Momoko Onodera +5
The dry release transfer of two-dimensional (2D) materials such as graphene, h-BN, and TMDs is a versatile method for fabricating high-quality van der Waals heterostructures. Up un…
Optical coupling between atomically-thin black phosphorus and a two dimensional photonic crystal nanocavity
Yasutomo Ota, Rai Moriya, Naoto Yabuki +5
Atomically-thin black phosphorus (BP) is an emerging two dimensional (2D) material exhibiting bright photoluminescence in the near infrared. Coupling its radiation to photonic nano…
