Abstract

A PbSe nanowire having an aspect ratio of about 100:1 and having a diameter of less than 20 nm. A PbSe nanowire produced by the process comprising reacting PbO with oleic acid in 1-octadecene or other non-coordinating solvent and producing Pb oleate in a flask, heating the Pb oleate to between 225 and 275 C under inert gas, injecting a first solution of Se dissolved in trialkylphosphine into the flask and producing a second solution, heating the second solution, maintaining the temperature >200 C in the flask, and resulting in PbSe nanowires.

Claims

exact text as granted — not AI-modified
1 . A PbSe nanowire having an aspect ratio of about 100:1 and having a diameter of less than 20 nm. 
     
     
         2 . The PbSe nanowire of  claim 1  having the ability to combine quantum confinement effects in two-dimensions with a long axis conducive to electron transport over macroscopic distances. 
     
     
         3 . A PbSe nanowire produced by the process comprising reacting PbO with oleic acid in a non-coordinating solvent and producing Pb oleate in a flask; heating the Pb oleate to between 225° C. and 275° C. under inert gas; injecting a first solution of Se dissolved in trialkylphosphine into the flask and producing a second solution; heating the second solution; maintaining the temperature greater than 200° C. in the flask; and resulting in PbSe nanowires. 
     
     
         4 . The PbSe nanowire of  claim 3  wherein the molar ratio of Pb:Se is between 1:1 and 5:1. 
     
     
         5 . The PbSe nanowire of  claim 4  wherein PbSe nanowires produced have the ability to combine quantum confinement effects in two-dimensions with a long axis conducive to electron transport over macroscopic distances. 
     
     
         6 . The PbSe nanowire of  claim 5  wherein the PbSe nanowires have a length of from about several hundred nanometers up to about 5 μm and have diameters less than about 20 nm. 
     
     
         7 . The PbSe nanowire of  claim 3  wherein the non-coordinating solvent is 1-octadecene.
