Nanographite Films for Solid State Electronic Applications

Abstract

The structure and properties of nanographite films useful for applications in solid state devices are described. The possibility to use low conducting state of nanographite film for detecting radiation in the segmented solid state detectors is considered. Other interesting phenomena include the field effect conductivity switching which can be used in contactless current limiters and circuit breakers, therf-to-dcconversion which can be utilized in microwave and photo detectors, and light emitting subsequent to the conductivity switching with possible application as light sources. The possible underlying gears of the mentioned effects are discussed.

“…39 While for paraffin/NG@SiO 2 , two strong peaks at 1585 cm −1 and 1348 cm −1 were observed, corresponding to the characteristic high purity graphite D peak (1348 cm −1 ) and G peak (1585 cm −1 ). 40 In addition, the Raman peaks at 1062 cm −1 and 1442 cm −1 assigned to the paraffin were also observed. The peak at 1585 cm −1 corresponds to an E 2g mode of single layer NG and is related to the vibration of sp 2 -bonded carbon atoms in a 2D hexagonal lattice.…”
