In a nanocarbon-producing device (173), a plane mirror (169) and a parabolic mirror (171) are arranged in a production chamber (107). Light, emitted from a laser light source (111), transmitted through a ZnSe window (133) is reflected at the plane mirror (169) and the parabolic mirror (171), collected at the parabolic mirror (171), and then irradiated onto the surface of a graphite rod (101).

Provided is a Si—Ge laminated thin film including at least one Si layer and at least one Ge layer, which are alternately laminated on a substrate (1). A Si layer (31) and a Ge layer (22) each have a thickness in a range of 5 to 500 nm. The Si layer (31) is amorphous and only the Ge layer (22) is crystallized. An average crystallite size of Ge in the Ge layer (22) is 20 nm or less.
摘要:
An electric double-layer capacitor includes a carbon composite electrode which serves as a polarizing electrode and made of a single-layer carbon nanohorn aggregate having a specific structure and a very large surface area. The single carbon nanohorn aggregate is mixed with a phenol resin, the mixture is formed and heated to produce a carbon composite electrode. The carbon composite electrode is impregnated with an electrolyte to become a polarizing electrode. An electric double-layer capacitor includes this polarizing electrode has a large capacitance and is capable of discharging with large current.
摘要:
An electronic equipment includes one or more electronic devices, a cold stage, and a cold insulation member. The one or more electronic devices perform a predetermined operation within a predetermined temperature range. The cold stage cools down the one or more electronic devices to a predetermined operational temperature at which the one or more electronic devices is operable. The phase transition temperature of the cold insulation member is in a range between the predetermined operational temperature and an upper limit of the predetermined temperature range. The cold insulation member is arranged adjacent to the one or more electronic devices, and retains the temperature of the one or more electronic devices within the predetermined temperature range. At least one electronic devices over which the cold insulation member is arranged is partially formed from a material which is in a superconductive state at the predetermined operational temperature.
