1. A na-atụle njikọ dị n'etiti PN junction diffusion current na voltaji junction, na njikọ a ga-egosi na ọ na-agbaso iwu nkesa nkọwa site na nhazi data;

2. A na-atụle Boltzmann mgbe niile nke ọma (Njehie ahụ ga-abụ ihe na-erughị 2%);

3. Mụta iji amplifier arụ ọrụ iji mepụta ihe ntụgharị voltaji ugbu a iji tụọ adịghị ike ugbu a site na 10^-6A ruo 10^-8A;

4. Mmekọrịta dị n'etiti PN junction voltaji na okpomọkụ na-atụle na uche nke junction voltaji na okpomọkụ na-agbakọ;

5. Odika iji gbakọọ oghere ike nke ihe semiconductor (silicon) na 0K.
