The secret sauce is in component selection and tuning. Opengeiger uses the BPW34 diode because it is relatively common and has a large surface area, but also because it has a very low capacitance ...

USTC team reports 2 kV/0.45 mΩ·cm 2 PiN diode with surge energy density of 282 J/cm 2 Researchers from University of Science ...

In essence, the four-layer diode was the first integrated circuit since it did the work of two transistors, two resistors, and a diode -- all in a single crystal. Unfortunately, they were so ...
