Bistable Nonvolatile Elastic-Membrane Memcapacitor Exhibiting a Chaotic Behavior

Abstract

We suggest a realization of a bistable non-volatile memory capacitor (memcapacitor). Its design utilizes a strained elastic membrane as a plate of a parallel-plate capacitor. The applied stress generates low and high capacitance configurations of the system. We demonstrate that a voltage pulse of an appropriate amplitude can be used to reliably switch the memcapacitor into the desired capacitance state. Moreover, charged-voltage and capacitance-voltage curves of such a system demonstrate hysteresis and transition into a chaotic regime in a certain range of ac voltage amplitudes and frequencies. Membrane memcapacitor connected to a voltage source comprises a single element nonautonomous chaotic circuit. arXiv:1103.0910v1 [cond-mat.mes-hall]

Kinks and antikinks of buckled graphene: A testing ground for the φ4 field model

“…This provides an access to intrinsic properties of graphene such as the intrinsic carrier mobility [1], mechanical strength [2] and thermal conductivity [3]. From the application point of view, multiple possible applications of suspended graphene have been proposed, among them are electromechanical resonators [4], electromechanical switchers [5], nanocantilever sensors [6], piezoresistive pressure sensors [7], capacitive pressure sensors [8], and capacitors with memory [9,10] (memcapacitors [11]) [39].…”

Memory Effects in Multi-terminal Solid State Devices and Their Applications

“…In his experiment in 1808, as recounted in the Philosophical Transactions for 1810 31 , Davy demonstrates a functional electric arc: "…charcoal, even when ignited to whiteness in oxymuriatic or muriatic acid gases, by the Voltaic battery, effects no change in them; if it has been previously free from hydrogen and moisture by intense ignition in vacuo. " This was better comprehended though in his 1812 book Elements of Chemical Philosophy 32 , where he writes "When pieces of charcoal about an inch long and one sixth of an inch in diameter, were brought near each other … a bright spark was produced, and more than half the volume of the charcoal became ignited to whiteness, and by withdrawing the points from each other a constant discharge took place through the heated air, in a space equal at least to four inches, producing a most brilliant ascending arch of light, broad, and conical in form in the middle. " Although, Davy originally exploited this incandescent device for electrolysis, his contributions are far more reaching.…”

“…al [8], and it is divided mainly in two categories: geometrical and permittivityrelated memcapacitors. An example of mem-capacitive switching device based on geometrical effects consists of a capacitor with a movable plate, whose movement depends on the applied electric field [32]. One such device would be a capacitor having one of the electrodes being elastic.…”

“…A memcapacitor proposed by Di Ventra et al [34], consists of a parallel plate capacitor with additional floating plates in between, separated by dielectrics. The internal charge can move between the different plates and its polar- The technique based on the Bosch process was first introduced by Milanovic et al [32] in an effort to fabricate lateral field emission devices. Doherty et al investigated the relationship between the SiNW diameter and the photoresist width and fabricated nanochannels utilizing ICP-DRIE [40].…”
