This Letter describes some electrical contact and \ntransport properties of ZnS single crystals having \nroom-temperature resistivities in the range of 1 to \n10 ohm-cm. Previous electrical transport measurements \non ZnS have been done mainly at high temperatures \nor under photoexcitation. Electrical \ncontacts to ZnS which display ohmic characteristics \nat room temperature have been described by Alfrey \nand Cooke. A serious limitation to a more extensive \ninvestigation of the electrical properties of ZnS \nhas been the difficulty in providing ZnS crystals \nwith contacts which would stay ohmic at low temperatures. \nIt has also been difficult to dope ZnS \nn-type without simultaneously introducing large \nconcentrations of native acceptor defects.
