Description
| Abstract: | This investigation explored the potential of a slab of porous silicon mounted onto a quartz crystal to detect various gas species or measure gas pressures for a given gas species. The pore sizes of the porous silicon are such that they should allow gas molecules to enter the silicon and thus change the mass of the silicon by a slight amount. This small mass change affects the frequency of oscillation of the quartz crystal which can be detected by a frequency counter. The strategy exploits the almost unique properties of the two materials: quartz crystal and porous silicon. |
