Yes is close but with a Z test alpha 5% the two values are not compatible. The error bars are large due to the instruments. The temperature is the same.
What do you think about my idea?
Hi, in laboratory i had a sample of Ge with p-doping. In a first place i have done different measure V vs I (first image)
Then i insert the sample in a magnetic field perpendicular to the sample.
And i have done measure of V vs B (with a fixed current at 8 mA) and i obtained the second image...
Hi, normally when we take a measure with a multimer we consider the error given by this type of tables:

Do you know how these errors are calculated?
Hi, this doubt is born because my professor has found this quadratic trend in this way (see the image)
But if we fit the dates with the function that i have written before we will not find the mobility that we have measure with the usual method but mobility/2. Why?
I’m looking at http://physics.gu.se/~tfkhj/161213.pdf , is it correct? It is not so easy but at first glance it seems that the final result is not a simple function, isn’t it?
Hi, we have done an experiment where we have to measure the resistance of a sample of Ge doping-p and how it changes due to a magnetic field perpendicular to the sample with a costant current.
We have found that R(B) has a quadratic trend (we have fit the dates with y = a[1+b*B^2] with a and b...
