In the referenced paper [1] , the micro-photograph shown in Fig. 1 (b) is of a representative HEMT. The measured HEMT of the paper has the following dimensions: ( ${\mathrm {LG}} =5\mu {\mathrm{ m}}, {\mathrm {W}} = 20\mu {\mathrm{ m}}, {\mathrm {LGS}} = {\mathrm {LGD}} = 6\mu {\mathrm{ m}}$ ). Fig. 1 has to be replaced with the corrected figure shown below:
