Hall effect

  1. Jan 16, 2010 #1
    I have a few questions about this effect. If I have some semiconductor of N type in which I have electrical field in x direction, and magnetic field in z direction



    Then Lorence force is in the -y direction because in N type of semiconductor [tex]n>>p[/tex] so


    And for this case Hall constant [tex]R_H=-\frac{1}{ne}[/tex] is negative. Am I right?

    And in same case but for P type Lorentz force will be


    so in y direction, and Hall constant

    All clear.
