Projects in which silicon and germanium use as a diode

[XuFyaN]

Homework Statement

Where can i study about those projects in which silicon and germanium use as a diode with their purpose in the appropriate project?

The Attempt at a Solution

I want the list of atleast 30 projects in which si & ge , i also wants to know for which purpose si & ge use in those projects..i searched a lot in books and internet but didn't find the answer anywhere.
Can anyone please guide me where i can find such projects.
Here is my efforts,

(1) Rectifiers in dc power supplies
(2) Zener diodes in voltage regulators
(3) Tunnel diodes as a relaxation oscillator at microwave frequencies.
(4) Light emitter diode in digital displays.
(5) Clipping and clamping networks.
(6) Varactor diode in tuning sections of radio and TV receivers.

can i consider these as projects ? and is there Si and GE diode presents in them ?
