Atoms are not added but rather the material (usually silicon) is doped with an impurity like germanium to either add an extra electron (n-material) or be missing an electron (p-material) in the outer valance shell.
A diode bridge modulator is one kind of balanced modulator.
The varactor diode is a semiconductor diode but in this kind, the capacitance is supposed to vary according to the applied voltage. It has an exponent factor that bears a negative fraction value.
It is an electronic device. A sort of one way valve for electricity.
Most of the Casio projectors use a 445nm laser diode that is rated at 1 watt. The projectors have the diodes running at 600mw for life.
When a diode passes from forward biased to reverse biased it takes a short period of time for the charge carriers in the vicinity of the junction to recombine and create a nonconducting depletion region. During this time period the diode conducts in the reverse direction, this is called the reverse recovery time. Its different for every kind of diode, to get the value for a specific diode consult the datasheet.
There is only one (chemical) kind of carbon atoms, they all are alike.
None, LASER diodes are solid state semiconductor devices.
Oxygen is composed of oxygen atoms.
Carbon Atoms :)
Atomic atoms were the first to form.
Metals lose electrons.
All elements are composed of atoms.
