Alloys for gas sensors investigated using the continuous gradient-high throughput screening macroscope CG-HTSM
- Ternary alloys have been studied as the gate metal of chemical sensors based on the field effect in silicon. The investigation of reduced poisoning of hydrogen sensors by H2S is presented in the alloy system PdxNiyCo1-x-y. A new method in high throughput screening of alloys is applied. Not singular sample compositions but a continuous gradient in alloy concentrations was produced on a semiconductor sample. A laser scanning system produces a photo current in the semiconductor to map the sensor signal and provide a quasi continuous alloy characterization. The new system is therefore called Continuous Gradient—High Throughput Screening Macroscope (CG-HTSM). Typically 625 alloys are characterized in 15 minutes. The resolution of our set-up allows distinguishing 100.000 alloy compositions.
