    摘要： The present invention relates to an apparatus for measuring the thickness of materials using the focal length of a lensed fiber and a method thereof. More particularly, the invention relates to a method of measuring the thickness of materials using the strength of the beam reflected from the focal length when the beam emitted from a lensed fiber is focused on a material. According to the present invention, the lensed fiber generates a form of Gaussian Beam and is attached to PZT 12 in order to detect the quantity of beam while the lensed fiber is moved vertically against the material to be measured.

    摘要： Disclosed herein is a method for manufacturing a zinc oxide semiconductor. The method comprises the steps of forming a zinc oxide thin film including a group V element as a dopant on a substrate by using a zinc oxide compound containing a group V element or an oxide thereof, charging the substrate having the zinc oxide thin film formed thereon into a chamber for thermal annealing, and thermal annealing the substrate in the chamber to activate the dopant, thereby changing the zinc oxide thin film exhibiting n-type electrical properties or insulator properties to a zinc oxide thin film exhibiting p-type electrical properties. According to the method, since a zinc oxide thin film exhibiting n-type electrical properties can be easily changed to a zinc oxide thin film exhibiting p-type electrical properties, the provision of holes required for optical devices is facilitated, thereby enabling the development of photoelectric devices such as light-emitting diodes, laser diodes and UV sensors and further extending applicability of the zinc oxide semiconductor.

    摘要： The present invention relates to a novel initiator for polymerizing polyisocyanate, more particularly to a metal amidate represented by the following Formula 1, which is useful for polymerizing polyisocyanate having a variety of functional groups, including alkyl and aryl, by anionic living polymerization. While the conventional initiators caused generation of dimer and trimer byproducts, the new initiator of the present invention facilitates polymerization of polyisocyanates having a variety of functional groups, including alkyl and aryl, since the amidate anion has a low reactivity, so that the control of initial initiation reaction rate and chain growth rate is easy, and the control of monodispersity and molecular weight is facile: 1 wherein M is an alkali metal such as Li, Na, K, and Cs, and R1 and R2 are independently an alkyl or aryl group group.
