Macroscopic Behavior and Microscopic Factors of Electron Emission from Chained Nanocarbon Coatings

Abstract

The carbyne-containing films based on linear-chain carbon are promising materials for the manufacture of electronic equipment components. These carbyne-containing materials can be used as active elements of computational electronics and as ultra-miniature sensors of gaseous environment. The temperature studies of the electrical characteristics of carbyne-containing films by most of the scientific groups are limited to the low temperature range in which the quantum properties of nanostructures are most pronounced. We studied carbyne-containing films with a thickness of 20 and 400 nm on copper and silicon substrates using optically stimulated electron emission (OSEE) in the temperature range from room temperature (RT) to 400 °C. Theoretical modeling explains the dependence of work function on termination groups and substrate lattice. Experimental data revealed a relationship between the spectral characteristics of electron emission and temperature. The spectral contributions of both surface states and bulk interband transitions were clearly distinguishable.

Tailoring Vibrational Signature and Functionality of 2D-Ordered Linear-Chain Carbon-Based Nanocarriers for Predictive Performance Enhancement of High-End Energetic Materials

“…The structure of the bonds in the grown carbon-based nanomatrices can be programmed by the processes of self-organization and autosynchronization of the growing nanostructures. A number of experimental studies show that the sp-bonds and the sp-hybridized carbon nanostructures are formed only in a narrow range of optimal ion-stimulated pulse-plasma deposition parameters and modes [ 33 ].…”

Optical and Electronic Properties of Carbon-Based Nanomaterials and Composites

“…Frontier 1D linear carbon chains produced by carbon plasma ion-stimulated condensation were studied both theoretically, by density functional theory, and experimentally in a temperature range up to 400 • C [8]. The reported results showed that a combination of substrate structure and terminal group type of the carbon chain influences the work function of the material, a property exploitable both for the electronic and sensing applications of these systems.…”
