Probe-tip mechanical wear is a fundamental issue facing probe-based storage, which can cause serious degradation of the write-read resolution over the device lifetime. HfB 2 conductive coatings grown at low temperatures using chemical vapor deposition possess high mechanical properties that are ideal for this technology. Here, we show that HfB 2 coated probe-tips can potentially enhance a previously demonstrated 5 km wear endurance mechanism developed using PtIr coated probe-tips to beyond 8 km, thereby increasing the lifetime of probe-based memory devices. We foresee the extension of this coating technology to other scanning probe based systems and nanoelectromechanical devices.
