Analysis of Lorentz Force in Semiconductor

[Petar Mali]

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

\vec{E}=E\vec{e}_x

\vec{B}=B\vec{e}_z

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

F_l=-e\vec{\upsilon_D}x\vec{B}

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

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

F_l=e\vec{\upsilon_D}x\vec{B}

so in y direction, and Hall constant

R_H=\frac{1}{pe}?

All clear.
