Are you kidding! The noise generated in a diode junction IS NOISE and is 
generated by the combination of electrones, if you can predict it ... man 
you'll gain the next 100 Nobel prices ;-))). Using a diode junction (amplifying 
the signal to the A/D range) and taking A/D samples is an EXCELENT way to 
generate real ramdom values.
