New quantum phases in a one-dimensional Josephson array

, 1997
We examine the phase diagram of an ordered one-dimensional Josephson array of small grains. The average grain charge in such a system can be tuned by means of gate voltage.

Coulomb Blockade and Hopping Conduction in Graphene Quantum Dots Array [PDF]

, 2011
We show that the low temperature electron transport properties of chemically functionalized graphene can be explained as sequential tunneling of charges through a two dimensional array of graphene quantum dots (GQD).

Enhanced Terahertz Spectroscopy of a Monolayer Transition Metal Dichalcogenide

Advanced Functional Materials, EarlyView.
An ad‐hoc engineered metallic surface is employed to perform enhanced terahertz spectroscopy of a monolayer transition metal dichalcogenide (TMD). Thanks to a local absorption boost of 104, this technique allows for the extraction of the phonon resonance features and effective permittivity of the 2D material, paving the way for the rational design of ...

Field - Programmable Gate Array [PDF]

, 2017
In this chapter, we describe the design of a field programmable gate array (FPGA) board capable of acquiring the information coming from a fast digitization of the signals generated in a drift chambers. The digitized signals are analyzed using an ad hoc real‐time algorithm implemented in the FPGA in order to reduce the data throughput coming from the ...

Interfacial Contact Engineering Enables Giant‐Performance Semiconductor Nanomembrane Optoelectronic Devices

Advanced Functional Materials, EarlyView.
This work investigates modifying interfacial contacts in realizing giant‐performance semiconductor nanomembrane optoelectronics. Strategies, including surface reaction and buffer layer work‐function modulation, are explored to boost the Schottky barrier. An emerging material of YbOx is utilized for near‐ideal Ohmic contact.

A synchronous binary array divider [PDF]

, 1974
An asynchronous binary divider formed of an array of identical logic cells is described. Each cell includes a single bit binary subtractor and a selection gate. The array is connected to divisor, dividend, quotient and remainder registers.

Noise-resistant control for a spin qubit array

, 2013
We develop a systematic method of performing corrected gate operations on an array of exchange-coupled singlet-triplet qubits in the presence of both fluctuating nuclear Overhauser field gradients and charge noise.

Tunable Tactile Synapses Enabled by Erasable Doping in Iongel‐Gated Nanotube Network Transistors

Advanced Functional Materials, EarlyView.
Artificial tactile synaptic sensors are realized by an iongel‐gated single‐walled carbon nanotube (SWCNT) transistor with reversible doping characteristics. The device senses and memorizes tactile stimuli and exhibits gate bias‐dependent excitatory or inhibitory synaptic behavior.
