Abstract

Optical and morphological properties of semi-transparent Caesium Iodide (CsI) thin films for three different film thicknesses deposited at a substrate temperature of 120 degrees C have been investigated. The photoemission properties were also studied to know the performance of such photocathodes. A comparison between the films deposited by keeping the substrate at room temperature (27 degrees C) and the films deposited at 120 degrees C is presented. Effect of substrate temperature on the morphological, optical and photoemission properties are presented. Optimization requirement of a semi-transparent photocathode for high sensitivity performance is discussed here.
