Phonon-Limited Transport in 2D Materials: A Unified Approach for ab initio Mobility and Current Calculations
Jonathan Backman, Youseung Lee, Mathieu Luisier
This paper presents an ab initio methodology to account for electron-phonon interactions in 2D materials, focusing on transition metal dichalcogenides (TMDCs). It combines density…
Field-Effect Transistors based on 2-D Materials: a Modeling Perspective
Mathieu Luisier, Cedric Klinkert, Sara Fiore +4
Two-dimensional (2D) materials are particularly attractive to build the channel of next-generation field-effect transistors (FETs) with gate lengths below 10-15 nm. Because the 2D…
Dynamics of van der Waals Charge Qubit in 2D Bilayers: Ab initio Quantum Transport and Qubit Measurement
Jiang Cao, Guido Gandus, Tarun Agarwal +2
A van der Waals (vdW) charge qubit, electrostatically confined within two-dimensional (2D) vdW materials, is proposed as building block of future quantum computers. Its characteris…
Efficient and accurate defect level modelling in monolayer MoS via GW+DFT with open boundary conditions
Guido Gandus, Youseung Lee, Leonard Deuschle +2
Within the framework of many-body perturbation theory (MBPT) integrated with density functional theory (DFT), a novel defect-subspace projection GW method, the so-called p-GW, is p…
Impact of Orientation Misalignments on Black Phosphorus Ultrascaled Field-effect Transistors
Cedric Klinkert, Sara Fiore, Jonathan Backmann +2
Two-dimensional materials with strong bandstructure anisotropy such as black phosphorus BP have been identified as attractive candidates for logic application due to their potentia…
Circuit-aware Device Modeling of Energy-efficient Monolayer WS Trench-FinFETs
Tarun Agarwal, Youseung Lee, Mathieu Luisier
The continuous scaling of semiconductor technology has pushed the footprint of logic devices below 50 nm. Currently, logic standard cells with one single fin are being investigated…
Efficient partitioning of surface Green's function: toward ab initio contact resistance study
Guido Gandus, Youseung Lee, Daniele Passerone +1
In this work, we propose an efficient computational scheme for first-principle quantum transport simulations to evaluate the open-boundary conditions. Its partitioning differentiat…
A cold-source paradigm for steep-slope transistors based on van der Waals heterojunctions
Demetrio Logoteta, Jiang Cao, Marco Pala +3
The availability of transistors capable of operating at low supply voltage is essential to improve the key performance metric of computing circuits, i.e., the number of operations…
Ab initio mobility of mono-layer MoS2 and WS2: comparison to experiments and impact on the device characteristics
Youseung Lee, Sara Fiore, Mathieu Luisier
We combine the linearized Boltzmann Transport Equation (LBTE) and quantum transport by means of the Non-equilibrium Green's Functions (NEGF) to simulate single-layer MoS2 and WS2 u…
