We investigated p-i-n nanojunctions made between aligned and crisscrossed functionalized tubes. A network of crisscrossed diodes exhibited current-voltage staircase curves at room and liquid nitrogen temperatures unlike its randomly oriented counterpart. This was also in contrast to the I-V curves of crisscrossed and coaligned contacts between tubes of the same type. It appears that the bias values, at which current steps occur, are separated by a multiple of 0.067 V. We attributed the voltage steps to the formation of quantum dot at the point of contact.
