Laser and Its Applications

pH Effect on the Size of Graphene Quantum dot Synthesized by Using Pulse Laser Irradiation

In this study graphene oxide (GO) was synthesized by using Hummer’s method. Low dimension graphene quantum dot nanoparticles (GQDs) were synthesized using pulse laser irradiation. Fourier Transform-Infrared Spectroscopy (FTIR), Ultraviolet-Visible (UV-Vis) spectroscopy and photoluminescence (PL) analysis were applied to study the GQDs characteristic. Scanning electron microscopy illustrated the...

Graphene polarity controllable amplifier and its applications

This paper exploits the unique ambipolar conduction property of graphene field effect transistors to realize a single transistor polarity controllable amplifier. The amplifier is polarity controllable since its small signal gain can be switched between positive and negative modes through proper biasing. Polarity controllable amplifiers can greatly simplify communication circuits in applications...

Impermeability of graphene and its applications

Article history: Received 2 April 2013 Accepted 26 May 2013 Available online xxxx This review discusses the genesis of impermeability in graphene and its extraordinary applications in fluid-encasement for wet electron-microscopy, selective gas-permeation, nanopore-bio-diffusion, and barrier coating against rusting and environmental hazards. As the thinnest material, graphene is composed of sp h...
