Abstract
A field emission device (10) includes a base (12), a conductive paste (16), and at least one carbon nanotube yarn (14). The at least one carbon nanotube yarn is attached to the base using the conductive paste. This avoids separation of the at least one carbon nanotube yarn from the base by electric field force in a strong electric field. A method for making the field emission device includes the steps of: (a) providing a base; (b) attaching at least one carbon nanotube yarn to the base using conductive paste; and (c) sintering the conductive paste to obtain the field emission device with the carbon nanotube yarn firmly attached to the base.
