a Schematic of a thin-film CNT solar cell. Adapted from [308]. b J–V characteristics of a CNT solar cell with area = 2.15 cm² (in red) and area = 0.06 cm² (in black). Adapted from [308]. c Schematic of a randomly connected 2D nanotube array that can be used as a crossbar switch. Here, CNTs self-assemble in the HfO₂ trenches with width of 70–300 nm. Adapted from [314]. d Schematic of an s-SWCNT-based wearable array of electronic devices, consisting of memory units, capacitors and logic circuits that can be integrated into different circuits for day-to-day applications. Adapted from [317]
