Imaging ballistic carrier trajectories in graphene using scanning gate microscopy
Sei Morikawa, Ziwei Dou, Shu-Wei Wang +6
We use scanning gate microscopy to map out the trajectories of ballistic carriers in high-mobility graphene encapsulated by hexagonal boron nitride and subject to a weak magnetic f…
Electric field modulation of Schottky barrier height in graphene/MoSe2 van der Waals heterointerface
Yohta Sata, Rai Moriya, Sei Morikawa +3
We demonstrate a vertical field-effect transistor based on a graphene/MoSe2 van der Waals (vdW) heterostructure. The vdW interface between the graphene and MoSe2 exhibits a Schottk…
Influence of the density of states of graphene on the transport properties of graphene/MoS2/metal vertical field-effect transistors
Rai Moriya, Takehiro Yamaguchi, Yoshihisa Inoue +4
We performed detailed studies of the current-voltage characteristics in graphene/MoS2/metal vertical field-effect transistors. Owing to its low density of states, the Fermi level i…
Edge-channel interferometer at the graphene quantum Hall pn junction
Sei Morikawa, Satoru Masubuchi, Rai Moriya +3
We demonstrate a quantum Hall edge-channel interferometer in a high-quality graphene pn junction under a high magnetic field. The co-propagating p and n quantum Hall edge channels…
Modulation of Schottky barrier height in graphene/MoS2/metal vertical heterostructure with large current ON-OFF ratio
Yohta Sata, Rai Moriya, Takehiro Yamaguchi +5
Detail transport properties of graphene/MoS2/metal vertical heterostructure have been investigated. The van der Waals interface between the graphene and MoS2 exhibits Schottky barr…
