Title:
PHOTOCATHODE
Document Type and Number:
Japanese Patent JPH11260248
Kind Code:
A
Abstract:
To obtain a photocathode whose temperature characteristics and sensitivity characteristics can be improved.
This photocathode 5 is formed on a compound semiconductor layer 5c and equipped with an alkali-metal containing layer 5d, which contains one or more components selected from a group comprising K-O, Na, Na-O, Li, Li-O, Rb and Rb-O. Temperature characteristic and sensitivity characteristic of this photocathode 5 can be improved more than those of the photocathode formed by using Cs as the alkali-metal containing layer 5d.
