Schottky effect questions

Hi,

Perhaps I don't understand Schottky effect so well. Must the metal be
a certain thickness? The following page shows some Schottky diode
history, which starts with the Cat's Whisker. Must the metal wire
(Cat's Whisker) that contacts the semiconductor be so thin? May I ask
why it must be thin? Then there's the point contact Schottky diode
that appears to have a thinly deposited metal. Perhaps the diode would
work if the deposited metal was very thick, but wouldn't it at least
still rectify to some degree?

One last question. Would the Schottky effect work if the metal was
say, Boron, which has extremely high resistance, ~ 1e+12 times higher
than copper?

Thanks for any help,
Paul
