A way to shrink micro circuitry smaller than previously thought has
been found. Nanometer size wires tend to exhibit
quantum mechanical behavior which affects their electrical
resistance. Resent experiments have shown that
adding phosphorus atoms to the wire prevents this from happening
since electrons in the phosphorus move more freely.
The development of computers is reaching the smallest size that circuits
can reach before affects of
quantum mechanics becomes an issue. This discovery reduces that
critical point further making possible increased miniaturization.
The ultimate solution is to develop quantum computers which are
currently are the earliest level of development but this discovery
expands the time available to develop quantum computers several more
years. |
