Thank you for your video, it was very helpful. Can you give me recommended science articles and/ or books that you have read to make this youtube video, please. It is for my own private research.

I'm very glad it was helpful for you! Lake Shore's marketing department worked with the application scientist Jeff Lindemuth to create this video. As a compliment to this video we have developed the Hall Effect Measurement Handbook which really digs deep into measuring the Hall effect. If you found this video to be interesting and helpful, you definitely should download our Hall Effect Measurement Handbook! tinyurl.com/y87gzys2

In the equation for Hall Coefficient you need the thickness of the sample as well.

Why are differences in these measurements taken into the resistance calculation? When I do this I get totally different answers compared by plugging in voltages/currents one by one and then averaging.

You use the absolute values of current and voltage, or do you need to pay attention to the signal of both measures?

Thank you for your video. Can I ask a question about calculate mobility and current density ? I measure hall effect about (Rxx or Rxy) - B curve . Someone will use the slope to calculate them . But ,I don't know how to prove the formula.

What is the ft meaning in van der pauws resistivity equation
@C4illin

f is one and t is thickness?
@LakeshoreCryo

In the equation, f is the solution to van der Pauw’s equation (geometry factor related to the sample) and t is the thickness of the sample.

What must be the polarity for the voltmeter?
@LakeshoreCryo
Жыл бұрын
If the polarity of the voltmeter is backwards, then a positive current will make a negative voltage, and the resistance will be negative. The polarity of the voltmeter should always be set correctly so that resistance are calculated as positive.

Thank you very much for the video. What does "f" in Van Der Pauw's Equation for Resistivity refer to?
@LakeshoreCryo
4 жыл бұрын
Good question Minh, and this information may need added to the video for further clarity. "f" refers to the symmetry of the sample. After speaking with our Hall expert, his explanation is as follows: "f" is determined by using Van der Pauw's equation for calculating "f". If f=1 the sample is symmetric; values less than 1 mean the sample is less symmetric. Please see the linked image: imgur.com/bGdF8Ik Hopefully that helps. If not, let us know and we'll provide further detail.
