Semiconducting compounds of palladium with sulfur and/or phosphorus were prepared as crystals and their semiconducting and photoelectrochemical properties studied. The compounds include PdS, PdPS, Pd/sub 3/(PS/sub 4/)/sub 2/ and crystal growth was accomplished by chemical vapor transport with halogens and Bridgeman methods. Photoelectrochemical techniques were used to measure bandgap, transition type, doping level, majority carrier type, flatband potential, quantum yield for electron flow, and stability in a photoelectrochemical cell. The previously undetermined bandgap of PdP/sub 2/ is reported (1.08 eV, indirect).
