As an example we now consider an abrupt one-sided p-n diode. The current is shown as function of the voltage in Figure 4.4.7. It is calculated for a rather low n-type doping of 10 13 cm -3 to further highlight the high injection effects.hen calculating the current in a p-n diode one needs to know the carrier density and the electric field throughout the p-n diode which can then be used to obtain the drift and diffusion current. Unfortunately, this requires the knowledge of the quasi-Fermi energies, which is only known if the currents are known.
Doctors often diagnose testicular torsion with a physical exam of your scrotum, testicles, abdomen and groin. Your doctor might also test your reflexes by lightly rubbing or pinching the inside of your thigh on the affected side. Normally, this causes the testicle to contract.
Sexual maturity has more to do with size than age. In the wild, a female tortoise will not lay eggs until around 15 years of age. However, in captivity, tortoises tend to grow faster and mature earlier.Females can lay eggs at around 14cm straight carapace length (SCL); however, breeding very young or very small tortoises is not to be encouraged as the female may experience difficulty in laying the eggs.owever, in captivity, tortoises tend to grow faster and mature earlier.
