1945 S. Benzer Photoelectr. Effects in Germanium (U.S. Dept. of Commerce, Office of Publication Board PB 28644) 3 In exploring germanium samples for their rectification at different points, uncommon current-voltage characteristics are sometimes observed. There are two types which are of particular interest because of their sensitivity to light... K. Lark-Horovitz has given the descriptive names ‘photodiode’ and ‘photopeak’ to these characteristics.
1961 G. R. Choppin Exper. Nucl. Chem. vii. 101 The increase in crystal dimensions results in an increase of the photopeak intensity at the expense of the Compton distribution.
2000 Limnol. & Oceanogr. 45 712/2 Uranium-238 activity in sediments was estimated by the 63.3 keV photopeak.
