Abstract

Hall sensors widely dominates the field of magnetic sensing. Basically, they produce information in terms of voltage with respect to applied field. The produced output depends on several parameters such as carrier mobility, carrier concentration, thickness and device geometries. In brief, materials with higher mobility and less thickness provides better candidates for such purposes. Looking at those parameters; gold-based Hall devices may not be thought of as the best candidate for magnetic field sensing. However, this does not suggest that it cannot be used for biosensing purposes. Gold presents an advantage of potential label-free biosensing device development since it can easily be functionalized for biosensing purposes. In this study, the feasibility of gold-based Hall devices was investigated through different fabrication techniques with and without adding separate layers including materials such as copper, nickel and chromium. The characterization has revealed that devices with smaller dimensions produce better output. The results showed that using gold to fabricate Hall sensors has merit for potential label-free biosensing purposes by designing a suitable geometry and following relevant microfabrication techniques.
