DC current measurements for home made diode: 12:10pm today, 10.3pA 4:00pm today, 19.4pA It seems to be jumping back and forth between ~ 10pA & 20pA. ...

Well this is interesting. The homemade diode current just tested a few minutes ago has made a jump to 20.6pA. Is this caused by an "energy jump?" This jumping to various levels has been been observer numerous times in diode experiments, but has always settled down at ~ 10pA. It should be pointed out that there was a ...

It just occurred to me that isolating the diodes or piezos from AC electrical noise (Johnson noise) is probably not going to work in terms of getting past the 10pA level. The parallel capacitance of my piezo is ~ 30nF. And the resistance of this piezo at such low current levels is in the giga ohm region. Therefore, ...

This morning the homemade was producing 9.7 pA. :-D ...

This is such an exciting moment for me!!! Maybe I should wait another day to be certain before celebrating, but it's looking great so far. Would you believe I'm celebrating over 10pA? That is correct, a few minutes ago the homemade diode was producing 10pA DC current!!! :-D This is so important for the research. It ...

Good news so far. ... knock on wood! About 1 or 2 hours ago the measured current was 7.9pA DC. A few minutes ago the measured current was 9.0pA DC. The current obviously bounced and ~ 2 years of diode testing experience tells me that it's trying to maintain the 10pA. Lets hope this homemade diode has what it takes to ...

Wow, the homemade diode current has made a sudden drop to 21pA! Just this morning, about 4.5 hours ago it was 79pA. This sudden rapid drop in current has me a bit concerned because at this rate it will go below 10pA. Although, I have seen a lot of diode experiments where the current will drop in jumps, as if there are ...
