摘要: The circular transfer length method was employed to extract the specific contact resistivity, ρc of GeTe (amorphous and crystalline state) with metals (Ni, W, TiW) quantify series resistance. amorphous-GeTe also determined for different annealing conditions. Higher metal work functions produce lower both states reduced further temperatures greater than crystallization temperature. This is suggested be a consequence higher temperature required diffuse sufficient interstitial metallic atoms transform covalent bonding at interface bonding.
