Title:
PHOTOCONDUCTIVITY ANTENNA, CAMERA, IMAGING APPARATUS, AND MEASURING DEVICE
Document Type and Number:
Japanese Patent JP2015142101
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a photoconductivity antenna capable of generating a terahertz wave with higher intensity by achieving a higher carrier mobility than the conventional.SOLUTION: The photoconductivity antenna 100, which is a photoconductivity antenna 100 generating a terahertz wave T with an optical pulse p irradiated, includes a first layer 10 that forms a carrier C with an optical pulse p irradiated; a second layer 20 that is positioned on the first layer 10 and has a higher carrier mobility than that of the first layer 10; and a first electrode 30 and a second electrode 32 that are positioned on the second layer 20 and are applied with a voltage to the second layer 20.
