Abstract: A deposition method includes: introducing a gas into an airtight container containing electrically insulated raw material particles to generate an aerosol of the raw material particles; transferring the aerosol to a deposition chamber through a transfer tubing connected to the airtight container, the deposition chamber having a pressure maintained to be lower than that of the airtight container; injecting the aerosol from a nozzle mounted on a tip of the transfer tubing toward a target placed on the deposition chamber to cause the raw material particles to collide with the target, thereby causing the raw material particles to be positively charged; generating fine particles of the raw material particles by discharge of the charged raw material particles; and depositing the fine particles on a substrate placed on the deposition chamber.

Abstract: A deposition method includes placing fine particles in an airtight container, the fine particles being obtained by forming a coating layer on a surface of a matrix, the coating layer being more liable to be charged than the matrix with respect to a material of a conveying path, generating an aerosol of the fine particles by introducing a career gas into the airtight container, transporting the aerosol via a transfer tubing to a deposition chamber which is maintained at a pressure lower than that in the airtight container while charging the fine particles by friction with the inner surface of the transfer tubing, the transfer tubing being connected to the airtight container and having a nozzle at the tip, and depositing the charged fine particles on a substrate placed in the deposition chamber by spraying the aerosol from the nozzle.

Abstract: An apparatus for manufacturing carbon nanohorns includes a production chamber configured to irradiate a solid carbon material with a laser beam to produce a product containing carbon nanohorns; and a separation mechanism configured to separate the product produced in the production chamber into a lightweight component and a heavyweight component. The heavyweight component includes carbon nanohorn aggregate with high purity, and high-purity carbon nanotubes can be obtained by collecting the heavyweight component.

Abstract: A deposition method is provided to enable fine particles having a relatively large particle diameter, for example, a diameter larger than 0.5 ?m, to be stably deposited on a substrate. The fine particles with insulating surface are placed in an airtight container, and a carrier gas is introduced into the container, triboelectrically charging the fine particles and generating an aerosol of the fine particles. The fine particles are charged by friction with the inner surface of a transfer tubing connected to the container, and the aerosol is conveyed via such tubing to a deposition chamber that is maintained at a pressure lower than that in the airtight container. The charged fine particles are deposited on a substrate placed in the deposition chamber.

Abstract: [Object] To provide a deposition method that enables fine particles having a relatively large particle diameter (at least larger than 0.5 ?m diameter) to be more stably deposited on a substrate by using a simple configuration. [Solving Means] In the deposition method, fine particles P whose surface is at least insulative are placed in an airtight container 2, and a carrier gas is introduced into the container, thereby triboelectrically charging the fine particles and generating an aerosol A of the fine particles. The fine particles in question are charged by friction with the inner surface of a transfer tubing 6 connected to the container, and the aerosol is conveyed via such tubing to a deposition chamber 3 which is maintained at a pressure lower than that in the airtight container. The charged fine particles are deposited on a substrate S placed in the deposition chamber.
