There were many crystals used in cat's whisker detectors
Picture shows some kind of zinc crystal unknown. Most of the
better crystals were never identified by radio hobbyist.

However Thomas Henry Moray was said to have developed a process
that improved electrical crystal properties. When stories went out that
he had succeeded his legend circulated beyond radio enthusiast. Later
Moray's claims gave oil and energy stock investors fear and those holding
the risk became curious and anxious. The sea of energy !

The development of semiconductors has a long history and some of it's research
has not been made public. Moray technology most likely has
areas that involve material science, uncommon magnetic processing equip,
unusual vacuum tube and electrical system that require thinking outside the box.
