Title: Efficient and versatile graphene-based multilayers for EM field absorption

Abstract

We thoroughly investigate the possibility to absorb most (i.e., up to more than 90%) of the incident electro-magnetic radiations in thin multilayered PMMA/graphene structures, thus proposing the technical realization of a device with an operational frequency range in the millimeter-wave domain, i.e., 30 GHz–300 GHz. Our simulations demonstrate the concrete possibility to enhance the field absorption by means of a selective removal and proper micro-pattering within the graphene material, enabling a complete and efficient control of the graphene sheet conductance. This method is applied to design and engineer a class of devices, endowed with a wideband operation capability, showing almost no fluctuations throughout the whole range of mm-wave frequencies.

  • The authors describe field modulated microwave absorption measurements on YBa{sub 2}Cu{sub 3}O{sub 7} / PrBa{sub 2}Cu{sub 3}O{sub 7} multilayers with PrBa{sub 2}Cu{sub 3}O{sub 7} thickness in the range 2.5 to 10 nm and with a fixed YBa{sub 2}Cu{sub 3}O{sub 7} thickness of 10 nm. The Fourier spectrum of the reflected microwave power reveals one fundamental frequency which appears at T{sub c} and even harmonics of the modulation field frequency {omega} at lower temperatures. The determination of the irreversibility line near T{sub c} for different values of the PrBa{sub 2}Cu{sub 3}O{sub 7} thickness and inferred from the vanishing of the nonlinearmore » response signal at 2{omega} in the presence of superimposed dc and modulation fields is reported.« less
  • Understanding the complex properties of electronic and spintronic devices at the micro- and nano-scale is a topic of intense current interest as it becomes increasingly important for scientific progress and technological applications. In operando characterization of such devices by scanning probe techniques is particularly well-suited for the microscopic study of these properties. We have developed a scanning probe microscope (SPM) which is capable of both standard force imaging (atomic, magnetic, electrostatic) and simultaneous electrical transport measurements. We utilize flexible and inexpensive FPGA (field-programmable gate array) hardware and a custom software framework developed in National Instrument's LabVIEW environment to perform themore » various aspects of microscope operation and device measurement. The FPGA-based approach enables sensitive, real-time cantilever frequency-shift detection. Using this system, we demonstrate electrostatic force microscopy of an electrically biased graphene field-effect transistor device. The combination of SPM and electrical transport also enables imaging of the transport response to a localized perturbation provided by the scanned cantilever tip. Facilitated by the broad presence of LabVIEW in the experimental sciences and the openness of our software solution, our system permits a wide variety of combined scanning and transport measurements by providing standardized interfaces and flexible access to all aspects of a measurement (input and output signals, and processed data). Our system also enables precise control of timing (synchronization of scanning and transport operations) and implementation of sophisticated feedback protocols, and thus should be broadly interesting and useful to practitioners in the field.« less
