On the low-temperature end, there are additional effects that allow devices to operate below their "freeze-out" temperature. First, if the semiconductor is doped to a certain concentration, it can attain degeneracy, a condition in which the dopants require no energy for ionization. For example, this happens in n-GaAs at a fairly low doping concentration (~1016 cm-3) that is common in standard devices. Thus, standard GaAs MESFETs can operate down to the lowest temperatures, essentially to absolute zero. For Si, degenerate doping requires a much higher a concentration (~1019 cm-3). On the other hand, there are effects that prevent operation even before the device is cooled to the "freeze-out" temperature. For example, standard Si bipolar transistors cease operating well above the Si "freeze-out" temperature, as described later.

Its official, excess doping can lead to degeneracy.

Ha. On a bike forum I saw summat similar where the correct number of bikes was determined to be n+1.

doesn't that have some connection with Huddersfield??

I'm sure I remember the aliens laughing their socks off at the inhabitants of Huddersfield.....

Just got a good one from 'Salvage Hunters' with Drew Pritchard and his mate 'T' who does all the donkey work & driving . Maybe you've seen it ? ( maybe not, might be a Wales thing ) .
After buying some signs & mirrors & stuff at an old fairground in Porthcawl, they set off for Conwy . 'T' who's driving, says :

Q : What did St. Patrick say to the snakes, as he was driving them out of Ireland ?
A : "Are you alright in the back there ? "

Yes Mark, we get Salvage Hunters here, used to watch it a lot.

Mostly 2-3-4 th generation repeats now.
