Abstract

A method of forming composite nanostructures using one or more nanomaterials. The method provides a nanostructure material having a surface region and one or more nano void regions within a first thickness in the surface region. The method subjects the surface region of the nanostructure material with a fluid. An external energy is applied to the fluid and/or the nanostructure material to drive in a portion of the fluid into one or more of the void regions and cause the one or more nano void regions to be substantially filled with the fluid and free from air gaps.

Claims (42)

1. A method of forming composite nanostructures with one or more nanomaterial, the method comprising:

providing a nanostructure material having a surface region and one or more nano void regions within a first thickness in the surface region;

subjecting the surface region of the nanostructure material with a fluid; and

applying an external energy to the fluid and/or the nanostructure material to drive in a portion of the fluid into one or more of the void regions and cause the one or more nano void regions to be substantially filled with the fluid and free from air gaps;

wherein the nanostructure material consists of semiconductor material and wherein the surface region of the semiconductor material has been subjected to a pattern and etch process to form the nano void regions.

2. The method of claim 1 wherein the nanostructure material comprises a nanoporous material.

3. The method of claim 1 wherein the external energy is provided at least by a process selected from thermal, electrical, optical, electro-chemical, mechanical, pressure, vacuum, or any one or more of these.

4. The method of claim 1 wherein the fluid further comprises a colloid material suspended in a liquid.

5. The method of claim 4 wherein the liquid is removed from the one or more nanovoid regions using at least vacuum, heat, or a combination.

6. The method of claim 5 wherein the colloid material remained after removal of the liquid is further subjected to a sintering process or a densification process.

7. A method of composite nanostructures with one or more nano material, the method comprising:

providing a nanostructure material having one or more nano void regions;

maintaining the nanostructure material in a vacuum environment;

subjecting a fluid to the one or more nanovoid regions while the nanostructure material is maintained in the vacuum environment to cause the one or more nano void regions to be substantially filled with the fluid free from air gaps;

wherein the nanostructure material is a semiconductor material and wherein the semiconductor material is subjected to a pattern and etch process to provide for the nanovoid regions.

8. The method of claim 7 wherein the vacuum environment removes trapped air/gas in the nano void regions.

9. The method of claim 7 wherein the maintaining is provided before the subjecting step.

10. The method of claim 7 wherein the fluid is further subjected to one or more heating steps.

11. The method of claim 10 wherein the one or more heating steps reduce viscosity and surface tension of the fluid and remove trapped gases within the nano void regions.

12. The method of claim 10 wherein the one or more heating steps are provided at a temperature ranging from about room temperature to about boiling point of the fluid.

13. The method of claim 7 wherein the nanostructure material is a nanoporous material.

14. The method of claim 7 wherein the fluid further comprises a colloid material suspended in a liquid.

15. The method of claim 14 wherein the liquid is removed from the one or more nanovoid regions using at least vacuum, heat, or a combination.

16. The method of claim 14 wherein the colloid material remained after removal of the liquid is further subjected to a sintering process or a densification process.

17. A method of forming composite nanostructures with one or more nanomaterial, the method comprising:

providing a nanostructure material having a surface region and one or more nano void regions within a thickness in a surface region;

introducing a fluid to a vicinity of the surface region;

maintaining the nanostructure material including the fluid at a first temperature, the first temperature being lower than at least a freezing temperature of the fluid;

providing the nanostructure material including the fluid in a vacuum environment while maintaining the nanostructure material at the first temperature ;

increasing the temperature of the nanostructure material from a first temperature to a second temperature; and

driving the fluid into the one or more nano void regions to substantially fill the one or more nano void regions with the fluid free of air gap,

wherein the maintaining of the nanostructure material including the fluid at a first temperature is provided before the driving of the fluid into the one or more nano void regions.

18. The method of claim 17 wherein the vacuum environment removes trapped air/gas in the nano void regions.

19. The method of claim 17 wherein the fluid is further subjected to one or more heating steps.

20. The method of claim 19 wherein the one or more heating steps reduce viscosity and surface tension of the fluid and remove trapped gases within the nano void regions.

21. The method of claim 19 wherein the one or more heating steps are provided at a temperature ranging from about room temperature to about boiling point of the fluid.

22. The method of claim 17 wherein the nanostructure material is a nanoporous material.

23. The method of claim 17 wherein the nanostructure material is a semiconductor material.

24. The method of claim 23 wherein the semiconductor material is subjected to a pattern and etch process to provide for the nano void regions.

25. The method of claim 17 wherein the fluid further comprises a colloid material suspended in a liquid.

26. The method of claim 25 wherein the liquid is removed from the one or more nanovoid regions using at least vacuum, heat, or a combination.

27. The method of claim 25 wherein the colloid material remained after removal of the liquid is further subjected to a sintering or a densification process.
