Enhanced gas sensing capabilities of diamond layers using Au nanoparticles
Original language description
The nanocrystalline diamond (NCD) film reveals a unique combination of physical, chemical, and optoelectronic properties, which makes it a promising material for various sensing applications. In this work, the NCD surface modification was achieved by a) layer morphology variation using two different types of chemical vapor deposition (CVD) systems, b) top surface termination, and c) Au nanoparticles (Au NPs). The properties of each structure are measured, compared and subsequently evaluated. The electrical properties are measured for two types of active gas in a temperature range from 22 °C to 125 °C. Neutral synthetic air was applied for flushing and resetting the sensors. Surface morphology greatly influences gas response because a large active surface area enhances interaction with gas molecules. While the termination of the NCD with hydrogen is essential for the functionality of the gas sensor, the Au NPs further enhanced the dynamic response of the sensor and magnitude.
