Electro-Thermal Analysis of Suspended Multiwalled Carbon Nanotubes

2020 IEEE MTT-S International Conference on Numerical Electromagnetic and Multiphysics Modeling and Optimization (NEMO), 2020
This paper studies the electro-thermal property of suspended multiwalled carbon nanotubes (MWCNTs) with high-bias voltages. A compact model of resistance with temperature-dependent parameters is employed for electric modeling of MWCNTs. In the thermal analysis, a compact model of thermal conductivity is considered and the finite difference method is ...

Modeling and analysis of electro‐thermal microactuators

Journal of the Chinese Institute of Engineers, 2009
Abstract This paper presents a dynamic model for analyzing the static and dynamic performance of electro‐thermal microactuators. In the proposed model, we adopt a lumped approach that decomposes the electro‐thermal‐mechanical system into a series of electrical resistors, heat resistors, heat capacitors, and a mechanical frame.

Size-Dependent Electro-Thermal Buckling Analysis of Flexoelectric Microbeams

International Journal of Structural Stability and Dynamics, 2023
This paper studies electro-thermal buckling in a flexoelectric microbeam. This first-of-a-kind study focuses on two case-specific types of buckling in microbeams, which are essential to microstructures. Because of the electric fields and high temperatures in their environments, microbeams are susceptible to electro-thermal buckling more often than ...

Analysis of electro-thermal instability in bipolar transistors

2015 IEEE International Conference on Electron Devices and Solid-State Circuits (EDSSC), 2015
This paper illustrates an analytical method to determine the electro-thermal instability due to self-heating and impact ionization in terms of dissipated power and junction temperature. The analysis is carried out for single transistors (corresponding to silicon and gallium arsenide technologies) as well as for scaled devices to appreciate the use of ...

Electro-thermal analysis of Electric Double-Layer-Capacitors

2008 14th International Workshop on Thermal Inveatigation of ICs and Systems, 2008
Electric double layer capacitors (EDLCs) operate between rechargeable batteries and electrolytic capacitors with respect to energy and power performance. Prediction of internal heating due to discharge and charge current cycles is one of key elements for producing reliable and safe devices with long cycle-life.

Electro-thermal analysis for automotive high power MOSFETs

2017 33rd Thermal Measurement, Modeling & Management Symposium (SEMI-THERM), 2017
Power dissipated within a semiconductor package must be properly extracted in order to guarantee safe and reliable operation in an automotive high power application. This work analyzes the transient thermal characteristics of two surface mount MOSFET packages types, TOLL and PQFN 5×6 for various heat sinking configurations.
