Various morphologies of the SWCNTs alignment with different pattern geometries: a \( {\text{W}}_{{{\text{SiO}}_{2} }} \):WPDMS = 500 nm:2000 nm. b \( {\text{W}}_{{{\text{SiO}}_{2} }} \):WPDMS = 750 nm:1250 nm. c \( {\text{W}}_{{{\text{SiO}}_{2} }} \):WPDMS = 1000 nm:500 nm. d \( {\text{W}}_{{{\text{SiO}}_{2} }} \):WPDMS = 2000 nm:500 nm. Note that the top panel indicates SEM image prior to the deposition while the bottom AFM images (phase mode) after the deposition. In the SEM images, the black region represents PDMS while the bright region SiO2. The scale bar is 500 nm
