ABSTRACTQuantum wires and dots were fabricated in one-dimensional conjugated polymer films by chemical vapor deposition. In the wires, a sharp exciton absorption peak, and in the dots, a blue shift in the absorption band due to electron confinement were observed. We showed that acceptors could be substituted into the conjugated polymer chain. We also demonstrated that molecular layer deposition (MLD), in which molecules are stacked on substrates one by one in order of preference in a vacuum, is feasible in fabricating one-dimensional conjugated polymers.

We report the growth, fabrication and characterization of GaInN/GaN multi-quantum well lasers grown on (00·1) sapphire substrates by low pressure metalorganic chemical vapor deposition. The threshold current density of a 1800 μm long cavity length laser was 1.4 kA/cm2 with a threshold voltage of 25 V. These lasers exhibited series resistances of 13 and 14 Ω at 300 and 79 K, respectively.
