According to a book about microwave and solid circuit I have read, the key structure of a varactor diode is its PN junction. When PN junction is reverse biased, we can make use of its potential barrier capacitance. In a word: a varactor diode is a PN junction device actually.
But I find another term: schottky varactor diode, in some other books. We know schottky barrier is a metal-semiconductor junction which is different from p-n junction, as I know.
Since "a varactor diode is a PN junction device actually" , how to explian "schottky varactor diode"?
