Hybrid Graphene Oxide and NTC Semiconductor Material Absorbs and Transform Light Energy via a Novel Surface Nanoscale Plasmon Mechanical

Abstract

Graphene oxide (GO) was prepared using the improved Hummer method, and mono-dispersed manganese cobalt nickel oxide (MCN) semiconductor nanometer particles were synthesized and coated with GO. Under 980-nm infrared laser excitation, this novel hybrid material demonstrated nanometer-scale surface plasmon resonance. The same mechanism has previously only been reported in good conductors. Although the MCN semiconductor is a negative temperature coefficient material, it can realize the same effect as a good conductor. The experimental data indicated that the hybrid material absorbed infrared laser photothermal energy with a transformation efficiency more than fourfold larger than that of pure mono-disperse MCN semiconductor nanopowder. The chain heat conductivity velocity of the hybrid material compares favorably with that of metal in that it alters the laser radiation energy heat transfer method on the surface. The hybrid material is one new kind of photothermal energy transfer material by new chain nanoscale surface plasmon mechanical, it can absorb sunlight and ultra-red light totally, and is one excellent energy transform and absorb material for sunlight.

Flexible Diodes/Transistors Based on Tunable p-n-Type Semiconductivity in Graphene/Mn-Co-Ni-O Nanocomposites

“…The carrier electrons in crystals will be scattered 10 12 -10 13 times per second, but because of the high electron mobility in graphene, electron scattering is strongly reduced. However, the electron space density of graphene is so large that diffusion is not the main effect [18,[20][21][22][23][24] and the electrons behave like a two-dimensional electronic fluid [25].…”

“…The Schottky contact barrier model is widely used to explain the interface carrier transport mechanism, which is generally based on thermionic emission. Although electron diffusion also occurs, the main contact mechanism between graphene and MCN is dominated by quantum tunneling because of the zero mass electrons of graphene ( Figure 2 ) [ 22 ].…”
