**ZnO nanoribbons with pseudoβrectangular crossβsections** (see Figure) are demonstarted to be excellent microcavities with a high quality factor (βΌβ3000). The lasing threshold is shown to be inversely proportional to the length of the ribbon for pumping intensities lower than the saturation region.
## Abstract We present a scanning tunneling microscopy and spectroscopy (STMβSTS) investigation of the effects of ultra high vacuum annealing and oxygen exposure onto ZnO nanoribbons synthesised by chemical vapour deposition. STM imaging revealed a width to height ratio for the nanoribbons between
