    • An X-ray control unit using a monocrystalline material which controls only a specific wavelength of X-rays, by using the monocrystalline material as a filter. The X-ray control unit includes a light source configured to generate X-rays, an X-ray control filter formed of a monocrystalline material having grown in one direction and configured to filter the X-rays generated by the light source to reflect and transmit characteristic X-rays, and an adjustor configured to adjust the light source and the X-ray control filter to arbitrary angles. Since X-rays having a specific wavelength can be selectively used by using a filter, the X-rays can be easily controlled and their intensity can be easily regulated. A characteristic line of the X-rays can be controlled and their intensity can be regulated without directly controlling an X-ray source.
    • 通过使用单晶材料作为过滤器,使用仅控制特定波长的X射线的单晶材料的X射线控制单元。 X射线控制单元包括被配置为产生X射线的光源,由单一晶体材料形成的X射线控制滤波器,该单晶材料在一个方向上生长并且被​​配置为滤除由光源产生的X射线以反射和透射 特征X射线,以及被配置为将光源和X射线控制滤波器调整到任意角度的调节器。 由于可以通过使用滤波器来选择性地使用具有特定波长的X射线,因此可以容易地控制X射线,并且可以容易地调节其强度。 可以控制X射线的特征线,并且可以在不直接控制X射线源的情况下调节其强度。

    • A field emission pixel includes a cathode on which a field emitter emitting electrons is formed, an anode on which a phosphor absorbing electrons from the field emitter is formed, and a thin film transistor (TFT) having a source connected to a current source in response to a scan signal, a gate receiving a data signal, and a drain connected to the field emitter. The field emitter is made of carbon material such as diamond, diamond like carbon, carbon nanotube or carbon nanofiber. The cathode may include multiple field emitters, and the TFT may include multiple transistors having gates to which the same signal is applied, sources to which the same signal is applied, and drains respectively connected to the field emitters. An active layer of the TFT is made of a semiconductor film such as amorphous silicon, micro-crystalline silicon, polycrystalline silicon, wide-band gap material like ZnO, or an organic semiconductor.
