Tunable graphene integrated metamaterial absorber is proposed for energy harvesting and visible light communication. The structure provides unity absorption in the visible spectrum in which it can be used perfect absorber for energy harvesting. In addition, it also provides tunability because of the graphene conductivity to be used as photoconductive or thermal switch for visible light communication.

Perfect metamaterial absorber-based energy harvesting and sensor applications in the industrial, scientific, and medical band
Bakir, Mehmet; KARAASLAN, MUHARREM; Dincer, Furkan; DELİHACIOĞLU, KEMAL; Sabah, Cumali (2015-09-01)
An electromagnetic (EM) energy harvesting application based on metamaterials is introduced. This application is operating at the the industrial, scientific, and medical band (2.40 GHz), which is especially chosen because of its wide usage area. A square ring resonator (SRR) which has two gaps and two resistors across the gaps on it is used. Chip resistors are used to deliver the power to any active component that requires power. Transmission and reflection characteristics of the metamaterial absorber for en...
Thin film (6,5) semiconducting single-walled carbon nanotube metamaterial absorber for photovoltaic applications
Obaidullah, Madina; Esat, Volkan; Sabah, Cumali (2017-12-01)
A wide-band (6,5) single-walled carbon nanotube metamaterial absorber design with near unity absorption in the visible and ultraviolet frequency regions for solar cell applications is proposed. The frequency response of the proposed design provides wide-band with a maximum of 99.2% absorption. The proposed design is also simulated with (5,4), (6,4), (7,5), (9,4), and (10,3) chiralities, and results are compared to show that the proposed design works best with (6,5) carbon nanotube (CNT) but also good for ot...
Electromagnetic energy harvesting and density sensor application based on perfect metamaterial absorber
Bakir, Mehmet; KARAASLAN, MUHARREM; Dincer, Furkan; Akgol, Oguzhan; Sabah, Cumali (World Scientific Pub Co Pte Lt, 2016-08-10)
The proposed study presents an electromagnetic (EM) energy harvesting and density sensor application based on a perfect metamaterial absorber (MA) in microwave frequency regime. In order to verify the absorption behavior of the structure, its absorption behavior is experimentally tested along with the energy harvesting and sensing abilities. The absorption value is experimentally found 0.9 at the resonance frequency of 4.75 GHz. In order to harvest the EM energy, chips resistors are used. In addition, the s...
Photonic Crystal and Plasmonic Silicon-Based Light Sources
Makarova, Maria; Gong, Yiyang; Cheng, Szu-Lin; Nishi, Yoshio; Yerci, Selçuk; Li, Rui; Dal Negro, Luca; Vuckovic, Jelena (2010-01-01)
Efficient silicon (Si)-compatible emitters can realize inexpensive light sources for a variety of applications. In this paper, we study both photonic crystal (PC) and plasmonic nanocavities that enhance the emission of Si-compatible materials. In particular, we examine the coupling of silicon nanocrystals (Si-NCs) to silicon nitride PC cavities and Si-NCs in silicon dioxide to plasmonic gratings, both for enhancement of emission in the visible wavelengths. In addition, we also observe the enhancement of the...
Quantum Transport Mode in Graphene Nanoribbon Based Transistor
Hedayat, Sayed Norollah; Ahmadi, Mohammad Taghi; Sedghi, Hassan; Goudarzi, Hadi; Moradi, Shahram (American Scientific Publishers, 2017-09-01)
Graphene has incredible carrier transport property with high application opportunity at single molecule level, which composes it as promising materials on nano electronic application. In order to develop the new device such as graphene nanoribbon transistor, Carbon Nanotube Field Effect Transistor (CNTFET) and nanowire based devices, it is essential to investigate the quantum limit in low dimensional systems. In this paper transmission coefficient of the schottky structure in the graphene based transistor i...
