Abstract
A nanoscale heterostructure tellurium-based nanowire structure, including a rod-like tellurium nanowire structure and a metal telluride agglomeration connected to the rod-like nanowire structure. The metal telluride agglomeration may have an octahedral shape or a platelet shape. The agglomeration structures are selected from the group comprising lead telluride, cadmium telluride, bismuth telluride, and combinations thereof.
Claims29
An ultrathin tellurium nanowire structure, comprising:
- a rod-like crystalline structure of tellurium, wherein the crystalline structure is defined by diameters of between 5-6 nm.
An ultrathin tellurium-based nanowire structure, comprising:
- a rod-like crystalline structure of one of lead telluride and bismuth telluride, wherein an ultrathin tellurium nanowire structure is used as a precursor to generate the rod-like crystalline structure.
A nanoscale heterostructure tellurium-based nanowire structure, comprising:
- a dumbbell-like crystalline heterostructure having a center rod-like portion;
- and
- at least one octahedral structure connected to each end of each of the center rod-like portions;
- wherein the center rod-like portion is a tellurium nanowire structure;
- and
- wherein the octahedral structures are one of lead telluride, cadmium telluride, and bismuth telluride.
A densified body, comprising:
- a grain boundary matrix;
- and
- a plurality of Te—Bi2Te3 particles distributed throughout the grain boundary matrix.
A nanoscale heterostructure tellurium-based nanowire structure, comprising:
- a rod-like tellurium nanowire structure;
- and
- a metal telluride agglomeration connected to the rod-like nanowire structure.
