Why we dont see any rectification effect?

  1. we fabricated a p-n junction in our laboratory.(metal-P-N-metal)
    aluminum was used as electrodes.
    electrical contact between "Al-P" is a blocking contact and "N-Al" is an ohmic one.
    we did not use two ohmic contactو
    We think that this can not be because we do not see rectification effect..
