Atomic Layer Deposition in Transistors and Monolithic 3D Integration

Advanced Functional Materials, EarlyView.
Transistors are fundamental building blocks of modern electronics. This review summarizes recent progress in atomic layer deposition (ALD) for the synthesis of two‐dimensional (2D) metal oxides and transition‐metal dichalcogenides (TMDCs), with particular emphasis on their enabling role in monolithic three‐dimensional (M3D) integration for next ...

Electro-Thermal Analysis of Oxide-Confined Vertical-Cavity Lasers [PDF]

physica status solidi (a), 2001
The performance of oxide-confined vertical-cavity lasers (VCLs) can be severely limited by current leakage and self-heating. This paper investigates electrical and thermal effects of lateral oxidation on wafer-bonded 1.55 μm VCLs. Measurements are combined with two-dimensional finite-element simulations to analyze internal device physics.

Curvature‐Tuned Friction at Electrified Ionic Liquid Interfaces

Advanced Functional Materials, EarlyView.
Graphene curvature plays a key role in friction electrotunability at single‐asperity contacts lubricated by ionic liquids. A 9 nm radius yields stronger tunability than larger radii, with distinct friction coefficients at low and high loads indicating a shift in the slippage plane.

Evaluating the Role of Entropy Change in Lithium-Ion Battery Electro-Thermal Modelling

Batteries
The accurate estimation of lithium-ion cell internal temperature is crucial for the safe operation of battery packs, especially during high discharge rates, as operating outside the safe temperature range can lead to accelerated degradation or ...

Electro-thermal analysis of the superconducting dipole circuit of SIS100

Journal of Physics: Conference Series, 2020
Abstract The heavy ion synchrotron SIS100, the core machine of the new international Facility for Antiproton and Ion Research (FAIR) in Darmstadt, is currently under construction. The 108 superconducting dipole magnets of SIS100 will be powered in series with a cycling rate up to 30kAs−1 which corresponds to 4Ts−1.

3D‐Printed Hygroscopic Polymer Networks for High‐Humidity Triboelectric Nanogenerators to Wirelessly Power Implantable Electronic Devices‐ A Conceptual Pathway

Advanced Functional Materials, EarlyView.
This work develops 3D‐printable tribopolymer networks that can enhance triboelectric performance under high humidity environments. Polar hydrophilic functional groups and incorporation of zwitterionic monomers promote bound‐water–dominated interfacial polarization thereby increasing electrical outputs.

AC analysis and simulation of smart electro-thermal microactuators

2012 IEEE International Conference on Industrial Technology, 2012
This work presents the AC analysis of smart microactuator system. The electro-thermal microactuator is modelled in VHDL-AMS and integrated with its driving circuit using Cadence AMS tools. A new design approach is used to generate a variable low frequency oscillator signal. The high voltage driving AC signal is generated by a DC/DC converter biasing an

A Universal Interfacial Dipole Strategy for Defect Suppression in Inverted Perovskite Solar Cells With Tunable Bandgaps

Advanced Functional Materials, EarlyView.
A 2D heterointerface with a two‐site anchor bridge suppresses nonradiative recombination at the perovskite/C₆₀ interface by reducing surface defects, elevating the Fermi level, and strengthening the electric field. This strategy enables efficient electron extraction, delivering 26.32% efficiency, 1.217 V Voc, excellent operational stability, and broad ...

Preheating Modeling of Forming Region and Design of Electrode Structure During Integral Electric Hot Incremental Forming

Nanomaterials
Recently, integral electric hot incremental forming technology has been proposed to form hard-to-form sheet metals and to eliminate some defects obtained through the local heating method via current, such as inhomogeneous temperature distribution, arc ...
