All-Carbon Negative Differential Resistance Nanodevice Using a Single Flake of Nanoporous Graphene

Abstract: A temperature-induced degenerate p-type graphene nanopore/reduced graphene oxide (GNP/rGO) heterojunction-based nanodevice was prepared and studied for the first time, showing a robust negative differential resistance (NDR) feature. In this regard, cellulose-based perforated graphene foams (PGFs), containing numerous nanopores (with an average size of ∼2 nm surrounded by nearly six-layer rGO walls) were synthesized using bagasse as a green starting material. The PGFs with an essential p-type semiconducting pro… Show more

“…They have demonstrated a record power density of 14 W g –1 higher than lithium-ion batteries (1.5 W g –1 ) and capacities of ∼300–3300 F that is greater than the conventional dielectric or electrolytic capacitors (2.7 F). Breakthroughs are rationally expected in case exceptional properties of two-dimensional (2D) can be exploited in this booming field of research. For instance, large specific surface area, high physical activity, strong chemical stability, and quantum confinement effects of graphene intrigued their usage in the electric double-layer capacitor (EDLC), owing to its unparalleled conductivity and low large-scale production cost, with a highest reported sCap of 200 F g –1 . ,, …”

“…Graphene can be divided into several types according to their morphologies and dimensions, such as 0D quantum dots, 1D nanoribbons, nanosheets, flakes, , 2D films, and 3D macroforms. The 0D quantum dots can be used in fluorescence imaging and light emission devices. The 1D nanoribbon provides a platform for topological insulators , and Dirac physics .…”

“…[31] Related theoretical investigation revealed the quantum transport regime and detailed band structures of NPG. [32] Also, NPG Esaki diodes were experimentally demonstrated, [33] which featured a negative differential resistance. However, we recognized the lack of efforts on applying NPG to memory devices and systems, [33][34][35][36][37] despite the rapidly increasing impact of nanomaterials-based memory technologies on both traditional electronics [33,38] and emerging neuromorphic computing systems.…”
