Undergrad Is there a Crookes radiometer device with photoelectric effect?

Click For Summary
The Crookes radiometer operates based on the differential heating of its black and white sides, causing it to rotate with the white side facing the light source. The discussion explores whether incorporating materials that exhibit the photoelectric effect would enhance the rotation speed. However, it is suggested that using different materials may not significantly impact the radiometer's performance. Understanding the fundamental mechanics of the radiometer is essential for evaluating any modifications. The conversation emphasizes the importance of the existing principles governing the device's operation.

TL;DR
I am looking for a device similar to a Crookes radiometer but using the photoelectric effect.
Physics news on Phys.org
Probably nor.
Do you understand why a radiometer turns in the directgion it does?, (White side forward) That's our starting point.
 

Thread 'One does not “prove” the basic principles of Quantum Mechanics'

I am slowly going through the book 'What Is a Quantum Field Theory?' by Michel Talagrand. I came across the following quote: One does not" prove” the basic principles of Quantum Mechanics. The ultimate test for a model is the agreement of its predictions with experiments. Although it may seem trite, it does fit in with my modelling view of QM. The more I think about it, the more I believe it could be saying something quite profound. For example, precisely what is the justification of...
