Electrical Conductivity of Rabbit and Cow Bones

Abstract

In this work the energy gap of rabbit and caw were obtained by using ultraviolet spectrometer, the energy gap for rabbit was found to be 4.22 ev while that of the caw is 5.3 ev. These band gaps mean that they are semi conductors with wide band gap. However the electrical techniques shows that the conductivity of rabbit starts to increase considerably above voltage of about 20 μv , while that of the cow is about 15 μv . This discrepancy can be resolved by bearing in mind that the ultra violet ray cannot easily excite impurities which contribute to conductivity considerably, while the electric can excite them to produce large amounts of free electrons .
