Semiconductors
Silicon,
a semiconductor -- sometimes conducts and sometimes does not
•When
semiconductors do and don’t conduct can be controlled
•The
degree to which semiconductors conduct can be enhanced
Ex.:
Use control to test Thai AND
cuisine
Send “yes” signal on wire
Make semiconductor conduct if “Thai” is found
Detect presence/absence of “yes”
Make semiconductor conduct if “cuisine” is
found
