2. INTRODUCTION
ABOUT XINTEK:
Xintek, Inc. is the world’s leading company
in making high quality carbon nanotubes
(CNTs) and CNTs based field emission
electron sources for a wide variety of
applications, including field emission x-ray
tubes and field emission displays, etc.
XINTEK’S CNT FIELD EMISSION
CATHODE TECHNOLOGIES:
Xintek’s CNTs based field emission
cathodes are fabricated using its
proprietary post deposition technologies
[1]. The technologies allow using of
preformed high quality CNTs as field
emission materials for the cathodes.
WHAT ARE UNIQUE ABOUT XINTEK’S
CNT FIELD EMISSION CATHODES?
What are unique about Xintek’s CNT field
emission cathodes are their superior field
emission performances. At Xintek, CNT
materials are produced using its
proprietary chemical vapor deposition
(CVD) process and have superb graphitic
structures [2]. It ensures enhanced
performances of the CNT field emission
materials, such as improved mechanical
strength, improved electric conductivity,
improved chemical and thermal stability,
etc. Both of Xintek’s CNT materials and
cathode fabrication process have been
studied and optimized for years based on
comprehensive research and development
efforts.
WHAT ARE FIELD EMISSION GRADE
CARBON NANOTUBES (FWNTS)?
The term “FIELD EMISSION GRADE
CARBON NANOTUBES (FWNTs)” refers
to a class of CNTs developed by Xintek
and its collaborator at Duke University for
field emission applications [2]. The
FECNTs present superior field emission
properties compared with other CNT
materials, including lower turn on field,
higher emission current and enhanced
emission stability, etc.
WHAT IS A DIODE CNT CATHODE?
Anode
CNT emitters
eDiode CNT
cathode
Substrate
A diode CNT cathode includes CNT field
emitters deposited on a conducting
substrate. The diode CNT cathode does
not included a gate electrode. To extract
electrons from the CNT cathode, a gate
electrode or an anode needs be integrate
with the diode CNT cathode.
