Thin film extraction
WebA thin-film flip-chip (TFFC) design with a roughened N-polar AlGaN surface can substantially improve this. We here demonstrate an enabling technology to realize TFFC LEDs emitting in the UVB range (280–320 nm), which includes standard LED processing in combination with electrochemical etching to remove the substrate. Web12 Apr 2024 · With a 1.2% O 2 ratio, the ITO thin film exhibits ~700 ohms/square sheet resistance and ~1.9 × 10 21 cm −3 electron concentration. The SPV measurement, shown in Fig. 2D, is for a device made of an ITO thin film with a 1.2% O 2 flow. For the low optical injection case, the near-surface potential change (of the order of microvolts) is far ...
