Thermal resistance at room temperature is mostly due to scattering by defects and interfaces. Now, heat dissipation in cryogenic electronic devices is demonstrated to be due to phonon black-body ...

The phonon black-body radiation limit becomes important when relevant length scales, such as the device and substrate dimensions and the spatial extent of the heat source 4, are smaller than the ...

The simple and elegant toy model for black-body radiation suggests that any hot object should spray out an infinite amount of gamma rays, which is not exactly what you want for a toaster oven.

Revise black body radiation for your physics GCSE foundation and higher triple science exams with Bitesize interactive practice quizzes covering feedback and common errors.

Hawking radiation is a type of electromagnetic radiation emitted by a black body, which is defined as a physical body, like a black hole, that absorbs all electromagnetic radiation. However black ...
