Shotkey diodes are common. Aka 1n5711. Widely used
in Rf and microwave.
They are low capacitance fast switching with low threshold.
Not Schottky diodes, but *Shockley* diodes, a close relative of a
diac. Genuine ones, circa late 1950's are very hard to find:

Schematic symbol looks like the number "4" with leads coming out of
the top and bottom.
Here's an application using some in an audio power amplifier:

Sometimes also called a "transistor diode" and once intended to
replace the 3-terminal transistor.
