Second-order Raman modes correlate with the electrical properties of reduced graphene oxide measured at nanoscale by atomic force microscopy.
Schematic representation of the flexible plasmonic graphene oxide (GO)/heterostructure-based device with dual functionality for electrochemical and SERS detection.
Carbon nanomaterials are important for future sensors and electronics. Defects determine the material properties, therefore, it is critical to find new ways investigate defects at nanoscale. In this context, Raman spectroscopy (RS) tool of choice study in carbon nanomaterials. On other hand, Kelvin probe force microscopy (KPFM) provides structural surface potential information Here, authors demonstrate synergistic application these methods investigation ion‐beam‐induced graphite. KPFM RS...
Raman spectroscopy (RS) is the tool of choice for analysis carbon nanomaterials. In graphene and nanotubes (CNT), RS provides rich information such as defect concentration, CNT chirality, layer number, doping, strain, other physical parameters interest. This work presents investigation a semiconducting film after high power laser irradiation. Changes were observed in D band revealing change concentration induced by laser. More importantly, it was found relative intensity decrease G − some...
The present study covers the nanoanalysis methods for four key material characteristics: electrical and electronic properties, optical, stress strain, chemical composition. With downsizing of geometrical dimensions electronic, optoelectronic, electromechanical devices from micro to nanoscale simultaneous increase in functionality density, previous generation microanalysis is no longer sufficient. Therefore, metrology materials' properties with resolution a prerequisite research development....
Graphene oxide (GO) offers excellent possibilities that are recently demonstrated in many applications ranging from biological sensors to optoelectronic devices. The process of thermal annealing aids removing the oxygen-containing groups GO, making GO more graphene-like, or so-called reduced graphene (rGO). Thermal reduction can also be achieved by intense light. Here, we demonstrate a scalable, inexpensive, and environmentally friendly method pattern films beyond diffraction limit light...
