# A semiconductor is a material that conducts electricity in specific circumstances. Therefore, depending on the conditions under which it is operating, it can act as a conductor or an insulator. Conductors are materials with many free electrons and/or holes that allow electrons to freely pass through it. An insulater has it's electrons firmly bound in it therefore does not allow electrons to pass through it.

# Bias voltage is the voltage it takes to get the diode to start conducting. Below a certain voltage, the diode will no work even in the forward direcction. It is the voltage which allows the electrons and holes to overcome the depleated zone and meet with each other, creating current.

# Bias voltage is the voltage it takes to get the diode to start conducting. Below a certain voltage, the diode will no work even in the forward direcction. It is the voltage which allows the electrons and holes to overcome the depleated zone and meet with each other, creating current. Reverse Biased means that the positive end of the battery is connected with the n-type semiconductor and the negative end is connected with the p-type semicondutor. This sucks all the electrons from the n-type reigion and filled in all the holes in the p-type reigion, creating a large depleated zone.

# Diode breakdown happens when a reverse biased diode is subjected to so much voltage that it conducts in the reverse direction. When a diode is biased past the bias voltage, it stays in a metaphysical state, so by itself, it would stay an insulater, but anything at all (such as a temperature fluctionation) would cause the diode to draw so much current that would cause excessive heat that will destroy a diode.
 +
# If a resister is placed in the circuit, it prevents the amperage to get too high and stops the diode from being fried. If the amps do get too high, then the resister would lower the voltage and the amps by creating resistance and turning the excess energy to heat.
 +
To make an avalanche-like pulse, you would also a capacitor that would be connected to the diode. It serves as a tempoary battery that allows the voltage and amperage to get high and create a pulse, then the capacitor will become drained and the resister would lower the voltage to below breakdown and the system would reset itself.
