On enhancing capability of tribocharge transfer of ZnO nanorod arrays by Sb doping for anomalous output performance improvement of triboelectric nanogenerators

Triboelectric nanogenerator (TENG) is an emerging green energy alternative, but the still low output power has been plagued by incomplete visualization into surface chemistry of materials. As an effective way of modifying surface chemistry for semiconductors by doping, we demonstrate that ZnO nanorod (NR) arrays doped into p-type with Sb can drastically enhance the output performance of TENG. The p-type characters of all the Sb-doped are...
