On-substrate Nanopattern Arrangement Technology
Daicel’s nanopattern arrangement technology allows each individual nanodiamond particle to be arranged precisely at any position on a solid substrate. This technology has made it possible to arrange nanodiamonds precisely in both line-and-space and dot array patterns at nanometer scale, instantly expanding the range of applications. For example, it is expected to be applied to the MEMS/NEMS diamond sensor with the highest sensitivity in the world.
Daicel’s unique nanostructure diamond manufacturing method
- Nanodiamond generation by the detonation method
- Arrangement of nanodiamonds at any position on a substrate at nanoscale
- Production of nanostructure diamonds by the chemical vapor deposition (CVD) method, using nanodiamonds arranged at nanoscale as seed crystals

Future fields of application stemming from on-substrate arrangement technology
- Electron emitting element
-
One of the properties of diamonds is the low-energy extraction of electrons from solids.
For example, using our arrangement technology, they can be used as LCD fluorescent pixels. - Single photon source
- This is a key to realizing quantum cryptographic communication and quantum computers. Diamonds that easily make photons and electron spins can be arranged, which allows production of elements for these systems.
- Nanoscale magnetic sensing
- Currently, the fields of application for magnetic sensors are expanding, from faint magnetism in living organisms to 3-dimensional magnetic imaging in electronic devices. Magnetically sensitive diamonds can be arranged precisely, which allows more accurate and detailed sensing of magnetic field information.
- Quantum bits
- To realize a quantum computer, the ultrafast computer of our dreams, quantum bits are required at the core of its operation. Various materials that can generate quantum bits have been proposed; however, they cannot be used in everyday environments because none of them operate unless cooled to tens or hundreds of degrees below zero. Diamonds are the only quantum bit material with the potential to perform at room temperature. In order to turn diamonds into quantum bits, it is necessary to arrange the NV centers, or impurity defects, within them in a regular manner, which is quite difficult. Our nanodiamond arrangement technology may enable this to be possible.
