Synthesis and properties of free-standing monolayer amorphous carbon
Chee-Tat Toh, Hongji Zhang, Junhao Lin +12
Bulk amorphous materials have been studied extensively and are widely used, yet their atomic arrangement remains an open issue. Although they are generally believed to be Zacharias…
Generation of sub-20-fs pulses from a graphene mode-locked laser
Ferda Canbaz, Nurbek Kakenov, Coskun Kocabas +2
We demonstrate, what is to our knowledge, the shortest pulses directly generated to date from a solid-state laser, mode locked with a graphene saturable absorber (GSA). In the expe…
Graphene Based Adaptive Thermal Camouflage
Omer Salihoglu, Hasan Burkay Uzlu, Ozan Yakar +7
In nature adaptive coloration has been effectively utilized for concealment and signaling. Various biological mechanisms have evolved that can tune the reflectivity for visible and…
Graphene Based Terahertz Phase Modulators
Nurbek Kakenov, M Said Ergoktas, Osman Balci +1
Electrical control of amplitude and phase of terahertz radiation (THz) is the key technological challenge for high resolution and noninvasive THz imaging. The lack of an active mat…
Controlling phase of microwaves with active graphene surfaces
Osman Balci, Nurbek Kakenov, Coskun Kocabas
In this letter, we report a method to control reflection phase of microwaves using electrically tunable graphene devices. The device consists of mutually gated large-area graphene…
Weighting graphene with QCM to monitor interfacial mass changes
Nurbek Kakenov, Osman Balci, Omer Salihoglu +3
In this Letter, using quartz crystal microbalance (QCM), we experimentally determined the mass density of graphene grown by chemical vapor deposition method. We developed a transfe…
