> Do transistors work without QM?
who knows?, if there is is QM and it's important
, the transistors might rely on them,
furthermore, if there is a God and transistors rely
upon him, then hey !, this _is_ deep ...
otherwise, so far, NO, the transistor is a
NPN or PNP device a'la whoever to claims to
have discovered it first. In modern processors
it's a NMOS or PMOS device, the gate being
insulated from the rest. A capacitance between the
gate & rest imposes a current consumtion proportional
to frequency+voltage, but , hey !, that's another story.

so far, improvement in conventional techinques has
given us the DRAM of increasing density, with sophistictaed
lithography. But, again the PQM dot computer is predicted
or maybe it's just another fantasy of mind, who knows ?

what is a 21264?, anyway, the basic material of
integrated circuits (IC's) is found in Sahara sand.
A little purification process applied to this 'sand'
gives us monocrystalline Si, that is a good starting
point for transistors & pentiums ...
No 'doping' problems in computer technology
