Table 3.

Results of particle size analysis carried out on data from surface topographs shown in Fig. 4 (a) to (d).

	Device A	Device B	Device C	Device D
Defects per 1 cm2	100	140	320	420
Height (µm)	2 (5)	4 (24)	2 (12)	3 (14)

Average values are shown outside and maximum values inside parentheses. Data was thresholded at 1 µm and image area remained fixed at 13.5 mm².
