Additive Manufacturing as a Means of Gas Sensor Development for Battery Health Monitoring

open access: yesChemosensors, 2021
Lithium-ion batteries (LIBs) still need continuous safety monitoring based on their intrinsic properties, as well as due to the increase in their sizes and device requirements.

Density-functional theory study of half-metallic heterostructures: interstitial Mn in Si

open access: yes, 2007
Using density-functional theory within the generalized gradient approximation, we show that Si-based heterostructures with 1/4 layer $\delta$-doping of {\em interstitial} Mn (Mn$_{\mathrm int}$) are half-metallic. For Mn$_{\mathrm int}$ concentrations of

Van der Waals Heterostructures Based on Allotropes of Phosphorene and MoSe2

open access: yes, 2017
The van der Waals heterostructures of allotropes of phosphorene (${\alpha}$- and $\beta-P$) with MoSe2 (H-, T-, ZT- and SO-MoSe2) are investigated in the framework of state-of-the-art density functional theory. The semiconducting heterostructures, $\beta$

Assessment of the notions of band offsets, wells and barriers at nanoscale semiconductor heterojunctions [PDF]

open access: yes, 2011
Epitaxially-grown semiconductor heterostructures give the possibility to tailor the potential landscape for the carriers in a very controlled way. In planar lattice-matched heterostructures, the potential has indeed a very simple and easily predictable ...

Advancing Electronic Application of Coordination Solids: Enhancing Electron Transport and Device Integration via Surface‐Mounted MOFs (SURMOFs)

open access: yesAdvanced Functional Materials, EarlyView.
The layer‐by‐layer (LbL) assembly of coordination solids, enabled by the surface‐mounted metal‐organic framework (SURMOF) platform, is on the cusp of generating the organic counterpart of the epitaxy of inorganics. The programmable and sequential SURMOF protocol, optimized by machine learning (ML), is suited for accessing high‐quality thin films of ...
