摘 要:DNA-based nanofabrication of inorganic nanostructures has potential application in electronics,catalysis,and *** DNA metallization has generated conductive DNA-assembled nanostructures;however,the use of semiconductors and the development of well-connected nanoscale metal-semiconductor junctions on DNA nanostructures are still at an early ***,we report the first fabrication of multiple electrically connected metal-semiconductor junctions on individual DNA origami by location-specific binding of gold and tellurium *** attachment to DNA origami was via DNA hybridization for Au and by electrostatic interaction for *** gold plating was used to create nanoscale metal-semiconductor interfaces by filling the gaps between Au and Te ***-point electrical characterization indicated that the Au-Te-Au junctions were electrically connected,with current-voltage properties consistent with a Schottky ***-based nanofabrication of metal-semiconductor junctions opens up potential opportunities in nanoelectronics,demonstrating the power of this bottom-up approach.
