在锌纳米晶镀层上热氧化时氧化锌纳米针的形成与生长机制

摘要

@@ Senuconductor ZnO has been widely studied as a short-wave-length light-emitting,transparent conducting and piezoelectric materials due to its wide bandgap(3.37 eV)with large exciting binding energy(60 meV)[1].There are many synthesis methods used for growing ZnO nanostructurc according to a so-called vaporliquid-solid(VLS)or vapor-solid(VS)mechanisms[2-3].
