Doping dependent plasmon dispersion in 2H-transition metal dichalcogenides

We report the behavior of the charge carrier plasmon of 2H-transition metal dichalcogenides (TMDs) as a function of intercalation with alkali metals. Intercalation and concurrent doping of the TMD layers have a substantial impact on plasmon energy and disp ...

Avalanche noise diodes: A compact circuit model compatible with advanced CAD tools

Christian Enz, Pierre-André Farine, Cyril Botteron, Gabriele Tasselli

This paper proposes, for the first time, a compact model for avalanche noise diodes that can easily be inserted in advanced CAD tools. The model is based on the theory of the Read type microwave avalanche diodes. It fully accounts for the electronic tuning ...

A Low Dark Count p-i-n Diode Based SPAD in CMOS Technology

Edoardo Charbon

In this paper, a novel CMOS single-photon avalanche diode (SPAD) is presented, and the device is designed using a vertical p-i-n diode construction. The p-i-n diode with a wide depletion region enables a low-noise operation. The proposed design achieves da ...

Efficient quantum mechanical simulation of band-to-band tunneling

Mihai Adrian Ionescu, Cem Alper, José Luis Padilla de la Torre, Pierpaolo Palestri

In this work, we extend an already existing simulator for tunnel FETs to fully take into account nonparabolicity (NP) of the conduction band in all aspects, namely the wave-function (WF) and density of states (DOS) corrections for both charge and BTBT curr ...

Competing charge, spin, and superconducting orders in underdoped YBa2Cu3Oy

Johan Juul Chang

To explore the doping dependence of the recently discovered charge-density-wave (CDW) order in YBa2Cu3Oy, we present a bulk-sensitive high-energy x-ray study for several oxygen concentrations, including strongly underdoped YBa2Cu3O6.44. Combined with previ ...

Leakage mechanisms in InAlN based heterostructures

Nicolas Grandjean, Jean-François Carlin, Marcel Py, Lorenzo Lugani

We propose a model for leakage currents in Schottky contacts on InAlN/GaN heterostructures based on two distinct tunneling mechanisms. Our modeling relies on structural parameters, in particular, InAlN dielectric constant, interface polarization charges an ...

Dynamical Coulomb Blockade Observed in Nanosized Electrical Contacts

Wolf-Dieter Schneider, François Patthey, I-Po Hong

Electrical contacts between nanoengineered systems are expected to constitute the basic building blocks of future nanoscale electronics. However, the accurate characterization and understanding of electrical contacts at the nanoscale is an experimentally c ...

Beyond Scaling

Luca De Michielis

Over the recent decades, the balance between increasing the complexity of computer chips and simultaneously reducing cost per bit has been accommodated by down-scaling. While extremely successful in the past, this approach now faces grave limitations leadi ...

Effect of the pn junction engineering on Si microwire-array solar cells

Anna Fontcuberta i Morral, Anna Dalmau Mallorquí, Franz Michael Epple

We report on the impact of the doping concentration design on the performance of silicon microwire arrays as photovoltaic devices. We have fabricated arrays with different p- and n-doping profiles and thicknesses, obtaining mean efficiencies as high as 9.7 ...
