Abstract

Purpose

The purpose of this paper is to deal with the self-heating of semiconductor nano-devices.

Design/methodology/approach

Transport in silicon semiconductor devices can be described using the Drift-Diffusion model, and Direct Simulation Monte Carlo (MC) of the Boltzmann Transport Equation.

Findings

A new estimator of the heat generation rate to be used in MC simulations has been found.

Originality/value

The new estimator for the heat generation rate has better approximation properties due to reduced statistical fluctuations.

The purpose of this paper is to set up a consistent off‐equilibrium thermodynamic theory to deal with the self‐heating of electronic nano‐devices.

Abstract

Purpose

The purpose of this paper is to set up a consistent off‐equilibrium thermodynamic theory to deal with the self‐heating of electronic nano‐devices.

Design/methodology/approach

From the Bloch‐Boltzmann‐Peierls kinetic equations for the coupled system formed by electrons and phonons, an extended hydrodynamic model (HM) has been obtained on the basis of the maximum entropy principle. An electrothermal Monte Carlo (ETMC) simulator has been developed to check the above thermodynamic model.

Findings

A 1D n+nn+ silicon diode has been simulated by using the extended HM and the ETMC simulator, confirming the general behaviour.

Research limitations/implications

The paper's analysis is limited to the 1D case. Future researches will also consider 2D realistic devices.

Originality/value

The non‐equilibrium character of electrons and phonons has been taken into account. In previous works, this methodology was used only for equilibrium phonons.

Abstract

Purpose

The purpose of this paper is to investigate the influence of contextual factors on the attribution of responsibility to female victims of an intimate partner violence (IPV) episode. The victim’s infidelity and the perpetrator’s alcohol abuse constituted the contextual factors in the investigation. The bystander’s age, gender, and attitude towards gender roles were predicted to influence the attribution of responsibility to an IPV victim, and their willingness to help.

Design/methodology/approach

An experimental study was conducted with 464 Italian participants with two independent conditions incorporated into a fictional scenario, measuring the different levels of the dependent variables under investigation. The participants were randomly assigned to different conditions provided their answers via an anonymous questionnaire.

Findings

The participants attributed more responsibility to the victim when they admitted infidelity, controlling for gender role norms and sexism. Attribution of responsibility, male gender, and attitudes towards the male gender role were significantly associated with less willingness to help the victim.

Practical implications

The results point to the importance of increasing the bystander’s role in preventing IPV by addressing gender role norms and their impact on the justification of violence.

Originality/value

The study complements the existing literature by providing new evidence of the barriers that prevent the bystander’s intervention in IPV episodes. A clearer understanding of these barriers will help to develop strategies that aim to prevent violence in the future.
