摘要：

The optical absorption edge of AgGaSe2 and AgGaS2 single crystals was measured as a function of hydrostatic pressure up to 30 GPa. in a gasketed diamond anvil cell. Both materials have several structural phase transitions in this pressure range and it has been established that the orthorhombic and tetragonal phases of AgGaSe2 and AgGaS2 at 300 K are indirect gap semiconductors.
