چکیده
In equilibrium, graphene nanostrips, with hydrogens sp2-bonded to carbons along their zigzag edges, are expected to exhibit a spin-polarized ground state. However, in the presence of a ballistic current, we find that there exists a voltage range over which both spin-polarized and spin-unpolarized nanostrip states are stable. These states can represent a bit in a binary memory device that could be switched through the applied bias and read by measuring the current through the nanostrip.

Graphene nanoribbon based negative resistance device for ultra-low voltage digital logic applications
Negative resistance devices offer opportunities in design of compact and fast analog and digital circuits. However, their implementation in logic applications has been limited due to their small ON current to OFF current ratios (peak to valley ratio). In this paper, a design for a 2-port negative resistance device based on arm-chair graphene nanoribbon is presented. The proposed structure takes...
متن کاملApplication of graphene toward digital electronic device and system
In this talk, applications of graphene for digital electronic devices are presented in three different ways; a channel material of FET, an gate electrode of FET, and an electromagnetic interference (EMI) shielding material. (1) Graphene, which presents remarkably high electron mobility, has come to the forefront as an alternative channel material for the post-silicon era. However, the natural l...
متن کاملNonvolatile memory cells based on MoS2/graphene heterostructures.
Memory cells are an important building block of digital electronics. We combine here the unique electronic properties of semiconducting monolayer MoS2 with the high conductivity of graphene to build a 2D heterostructure capable of information storage. MoS2 acts as a channel in an intimate contact with graphene electrodes in a field-effect transistor geometry. Our prototypical all-2D transistor ...
متن کاملPhotoresponse of La1.85Sr0.15CuO4 nanostrip
We report the fabrication and photoresponse of 5nm thick La1.85Sr0.15CuO4 nanostrip with a width of 100nm. The I-V characteristics of the nanostrip show a hysteresis and a sharp voltage jump at Ic. The Jc(3K) of the nanostrip is 2.3 × 10 A/cm. The nanostrip exhibits photoresponse signals when illuminated by a pulse laser at 1560 nm wavelength with a bias current just below Ic. The height of the...
متن کاملGraphene nano-floating gate transistor memory on plastic.
A transparent flexible graphene nano-floating gate transistor memory (NFGTM) device was developed by combining a single-layer graphene active channel with gold nanoparticle (AuNP) charge trap elements. We systematically controlled the sizes of the AuNPs, the thickness of the tunneling dielectric layer, and the graphene doping level. In particular, we propose that the conductance difference (i.e...
