Jawoll, es wuerde :)

I remember my old radio days. My audion and diode receivers never
would work with silicon only with germanium diodes and transistors.

The difference is the voltage threshold where the device would start
conducting. That is 200 mV for germanium but 800 mV for silicon.

Devices running with silicon and 2.4 volts will go down to 600 mV. That
means power consumtion will drop to 1/4. The real thing is a bit more
complex but for a guesstimation ...
