| Abstract Title: |
W35 - Noise Fundamentals, SN – Using Shot Noise to find “e” the Charge on the Electron |
| Abstract: |
Many instructors, and some students, have heard of Johnson-noise and shot noise in electric circuits, TeachSpin's apparatus provides a way to study both in detail in a trouble-free experimental arena. Students can see electrical noise, and measure spectral noise density, right from its definition. In this workshop, participants will make the kind of quantitative measurements of the shot noise present in a photocurrent that can be yield the fundamental charge 'e' to a precision of a few percent.
Participants will:
• Follow a noise signal from birth to quantitative measurement
• Learn how noise density is defined and measured
• Learn how shot noise is generated and measured
• Deduce a value of the fundamental charge 'e' |
