incorporating light into every logic gate. Traditional inverters – NOT gates – are already made with diodes (typically not light-emitting), resistors (typically not light-dependent), and ...

Usually, this would be little cause for celebration, but this is not like any clock you ... possible to make AND and OR gates using only diodes, a universal logic gate – NANDs and NORs ...

Consequently, nobody has been able to make reliable diodes ... to make a logic gate from a single nanowire using a different arrangement of contacts, although it is not clear how scalable this ...
