Then the diode was known as a "valve," because it forced current in the tube to travel exclusively in one direction. Getting that single directional flow was critical for radio sets which needed ...

preventing current flow. But if you reverse polarity, that oxide layer breaks down and current flows. To [Hales] this sounded like it could also act as a diode and so he went to work doing plenty ...

The diode has a very high resistance in one direction. This means that current can only flow in the other direction. This is the graph of current against voltage for a diode. Normally a diode will ...

Diode The diode is a two-terminal electronic component that ... Resistor The resistor is a passive electrical component that introduces resistance to the flow of electric current in an electrical ...

“Our work represents a proof-of-principle for compact low-threshold diode-pumped orange and red samarium lasers.” Into the orange According to the paper, laser emission at orange wavelengths (defined ...
