Abstract
| - To realize nanoscale wiring in two dimensions (2D), the fabrication of interconnected one-dimensional (1D)molecular lines through the radical chain reaction of alkene molecules (CH2CHR) on the H-terminatedSi(100)−(2 × 1) surface have been investigated using scanning tunneling microscopy (STM) at 300 K. Bythe judicious choice of R in the CH2CHR molecule and by creating a dangling bond (DB) at a desiredpoint using the STM tip, the perpendicularly connected allyl mercaptan (ALM) and styrene lines have beenfabricated on the Si(100)−(2 × 1)−H surface. The continuous growth of the styrene line at the end DB ofa growing ALM line (or vice versa) does not occur, perhaps, due to steric hindrance or/and interaction betweenadsorbed molecules.
