  • How to determine the concentration and sign of the charge

     ·  begingroup Hmm i mean if we assumed a uniform magnetic field with magnitude 0.4 T and we run a 75 A current in the X direction then the potential at the bottom of the slab is 8.1 10 -7 V higher than at the top. Plugging and chugging with those values makes n= 11.6 10 28. Which is close to the actual value of the concentration of the charge carriers in copper.

  • Measurement of Copper in p-Type Silicon Using Charge

    We compare SPV technique with µ−PCD for the determination of recombination activity of copper precipitates in p-Si. The copper precipitates were formed in bulk silicon through illumination at room temperature. We observed that the recombination activities of copper precipitates measured with SPV are higher than the ones measured with µ−PCD technique.
