Diamond nanofeather structure lays ground for low-cost fabrication of energy storage devices

In a recent study published in Diamond and Related Materials, researchers report that with specific pore size and ease of fabrication, diamond nanofeathers could be a great material choice for supercapacitors, batteries, sensors, and solar cells etc.

Scientific Achievement

A unique diamond nanofeather structure, distinct from conventional ultra- and nanocrystalline diamond (UNCD and NCD) structures, offers ease of fabrication, a high density of nanopores, and a 300-fold increase in capacitance.

Significance and Impact

The electrochemical etching method employed may offer a low-cost alternative to traditional diamond nano–structure fabrication techniques, eliminating masks and templates, and resulting in high performance materials.

Research Details

  • We fabricated and analyzed samples produced from NCDs grown on boron doped Si wafers, both etched and unetched, and compared a series of DNF samples with varied etch times.  
  • This work used Raman spectroscopy and high resolution SEM resources at the Center for Nanoscale Materials.

Work was performed in part at the Center for Nanoscale Materials.
