Title:
CARBON NANOTUBE FILM, TERAHERTZ WAVE DETECTION DEVICE, AND PN JUNCTION FORMING METHOD FOR CARBON NANOTUBE FILM
Document Type and Number:
WIPO Patent Application WO/2018/207780
Kind Code:
A1
Abstract:
Provided are: a carbon nanotube film capable of controlling the Fermi levels of carbon nanotubes; a terahertz wave detection device; and a PN junction forming method for carbon nanotube films. The carbon nanotube film (10) comprises, inside the membrane: a P-type semiconductor region (11); an N-type semiconductor region (12); and a PN junction (13) at which the P-type semiconductor region (11) and the N-type semiconductor region (12) come in contact. The site at which the N-type semiconductor region (12) is formed comprises a complex of: carbon nanotubes; and a crown ether (30) containing an ion liquid (20) and/or cations. The terahertz wave detection device (100) comprises a first electrode (2) and a second electrode (3) arranged facing each other and sandwiching the PN junction (13) therebetween, upon a two-dimensional plane of the carbon nanotube film (10).
