Thermal Force Imaging of Hot Electrons in Operando Nanodevices [PDF]

Nature Communications
The relentless pursuit of smaller, faster nanoelectronics concentrates intense heat at nanometer scales, threatening performance and reliability. Yet directly mapping this heat from nonequilibrium hot electrons has remained elusive. Here we introduce the

Electro-Thermal Analysis of Multi-Fin Devices [PDF]

IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2008
As device dimensions shrink into the nanometer range, power and performance constraints prohibit the longevity of traditional MOS devices in circuit design. FinFETs, a quasi-planar double-gated device, has emerged as a replacement. While flnFETs provide promising electrostatic characteristics, they have the potential to suffer from significant self ...

Simulation analysis of the electro-thermal performance of SOI FinFETs [PDF]

2016 Joint International EUROSOI Workshop and International Conference on Ultimate Integration on Silicon (EUROSOI-ULIS), 2016
The GSS `atomistic' simulator GARAND has been enhanced with a thermal simulation module to investigate the impact of self-heating on FinFET DC operation. This thermal simulation module is based on the solution of the coupled Heat Flow, Poisson, and Current Continuity Equations, which is developed for the benefit of computational efficiency.
