The limits of Near Field Immersion Microwave Microscopy evaluated by imaging bilayer graphene Moiré patterns
Douglas A. A. Ohlberg, Diego Tami, Andreij C. Gadelha +11
Molecular and atomic imaging required the development of electron and scanning probe microscopies to surpass the physical limits dictated by diffraction. Nano-infrared experiments…
Gate-tunable non-volatile photomemory effect in MoS transistors
Andreij C. Gadelha, Alisson R. Cadore, Kenji Watanabe +5
Non-volatile memory devices have been limited to flash architectures that are complex devices. Here, we present a unique photomemory effect in MoS transistors. The photomemory…
Local photodoping in monolayer MoS2
Andreij C. Gadelha, Alisson R. Cadore, Lucas Lafeta +4
Inducing electrostatic doping in 2D materials by laser exposure (photodoping effect) is an exciting route to tune optoelectronic phenomena. However, there is a lack of investigatio…
Lattice dynamics localization in low-angle twisted bilayer graphene
Andreij C. Gadelha, Douglas A. A. Ohlberg, Cassiano Rabelo +20
A low twist angle between the two stacked crystal networks in bilayer graphene enables self-organized lattice reconstruction with the formation of a periodic domain. This superlatt…
Probing the Electronic Properties of Monolayer MoS via Interaction with Molecular Hydrogen
Natália P. Rezende, Alisson R. Cadore, Andreij C. Gadelha +8
This work presents a detailed experimental investigation of the interaction between molecular hydrogen (H) and monolayer MoS field effect transistors (MoS FET), aiming…
Reversible doping of graphene field effect transistors by molecular hydrogen: the role of the metal/graphene interface
C. L. Pereira, A. R. Cadore, N. P. Rezende +5
In this work, we present an investigation regarding how and why molecular hydrogen changes the electronic properties of graphene field effect transistors. We demonstrate that inter…
