Self-heating structural materials, being useful for deicing and space heating, are reviewed. They include cement–matrix and polymer–matrix composites that are rendered self-heating through enhancing their effectiveness for resistance heating. The enhancement is attained by the use of electrically conductive fibers (continuous or discontinuous) and interlayers. The interlaminar interface between...

   Self-heating leads to a temperature rise of the laser diode and limits the output power and efficiency due to increased loss and decreased differential gain. To control device self-heating, it is required to design the laser structure with a low optical loss, while the heat flux must spread out of the device efficiently. In this study, a new asymmetric waveguide design is proposed and th...

This paper investigates whether the self-heating effect in short intra-block wires will become apparent with technology scaling. These wires seem to have good thermal radiation characteristics, but we validate that the self-heating effect in local signal wires will be greater than that in optimal repeater-inserted global wires. Our numerical experiment shows that the maximum temperature increas...

Self-heating phenomena are studied from room down to near liquid helium temperatures in fully depleted N channel thin film SIMOX MOS devices. A simple theoretical analysis of the self-heating effect is worked out. A method for the extraction of the thermal resistance and the device temperature rise directly from the static output characteristics is derived. Also direct self heating transient me...

This paper proposes a positive temperature coefficient (PTC) self-heating method, in which EVs can be operated independently of external power source at low temperature, with a lithium-ion battery (LIB) pack discharging electricity to provide PTC material with power. Three comparative heating experiments have been carried out respectively. With charge/discharge tests implemented, results demons...

Introduction More and more eco-feedback technology is being implemented to support people’s self-awareness regarding water, heating or energy consumption. Although eco-feedback technologies have managed to raise awareness (e.g, using visualisations [7]) about consumption, many challenges still remain. For instance, people still experience disengagement using technology [16, 1] as it is di cult ...

We present the design and simulation of a single-walled carbon nanotube(SWCNT)-based field-effect transistor (FET) using Silvaco TCAD. In this paper, theself-heating effect modeling of the CNT MOSFET structure is performed and comparedwith conventional MOSFET structure having same channel length. The numericalresults are presented to show the self-heating effect on the I...

Thermistors are very commonly used for narrow temperature-range high-resolution applications, such as in medicine, calorimetry, and near ambient temperature measurements. In particular, Negative Temperature Coefficient (NTC) thermistor is very inexpensive and highly sensitive, whose sensing temperature range and sensitivity are highly limited due to the intrinsic nonlinearity and self-heating p...
