CdTe Detector
Electrode Selection for CdTe Detector
We have three types of CdTe detectors:
In Schottky detectors
In (Indium) and Pt (Platinum) electrodes are formed on the detectors.
Its Schottky barrier diode characteristics enable minimizing dark current by applying reverse bias.
The dark current is smallest among three.
Indium electrode (anode) cannot be patterned with photolithography; therefore, the 2D detector obtains radiographs through hole collection.
Al Schottky detectors
Al (Aluminium) electrodes and Pt (Platinum) electrodes are formed on the detector.
Its Schottky barrier diode characteristics enable minimizing dark current by applying reverse bias.
Al electrodes (anode) can be patterned with photolithography; therefore, the 2D detector obtains radiographs through electron collection
Patterned electrodes can be formed on both sides of a detector like cross-strip detector.
Pt Ohmic detectors
Pt (Platinum) electrodes are formed on both side of the detector.
Its Ohmic characteristics are suitable for low bias operation and long-term stable operation.
Patterned electrodes can be formed on both sides of a detector like cross-strip detector.
