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…
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…
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…
Photo-thermoelectric detection of cyclotron resonance in asymmetrically carrier-doped graphene two-terminal device
Kei Kinoshita, Rai Moriya, Miho Arai +4
Graphene is known to show a significant photo-thermoelectric effect that can exceed its photovoltaic contribution. Here, by utilizing this effect, we demonstrate a photovoltage mea…
Heat transfer at the van der Waals interface between graphene and NbSe2
Yohta Sata, Rai Moriya, Naoto Yabuki +2
Graphene has been widely used to construct low-resistance van der Waals (vdW) contacts to other two-dimensional (2D) materials. However, a rise of electron temperature of the graph…
