In this lesson, students build two circuits and explore how transistors function. When Bell Labs introduced the transistor in June of 1948, a spokesman proudly announced "This cylindrical object . . .

Thermal sensing and imaging are playing increasingly important roles in intelligent systems 1,2,3,4,5,6. Thermal imaging can function in low visibility by collecting emission from objects in the ...

“Three-terminal thermal analogies to electrical transistors have been proposed for use in thermal amplification, thermal switching, or thermal logic, but have not yet been demonstrated experimentally.
