• Proposed electrothermal immersion probe sensor can become the standard characterization technique at temperatures >700 oCo Addresses key challenges present in current state-of-the-art techniques
• The modified Xenon flash technique could serve to benchmark high temperature characterization of solidso Versatility - its can be useful for other high temperature applications
