Title: Radiation detecting apparatus
Inventor: SATO KENJI
IPC: H01L27/146
Filed: 2000-08-24
Abstract: PURPOSE: To obtain a radiation detector in which creeping discharge due to a bias voltage applied to a radiation sensitive semiconductor film is retarded. CONSTITUTION: The inventive radiation detector comprises a carrier selective high resistance film 1A formed on the entire surface between a radiation sensitive semiconductor film 1 and a voltage applying electrode 2, and a region 2A formed with no electrode is provided on the entire circumference of the voltage applying electrode 2. Dark current can be suppressed by the carrier selectivity of the carrier selective high resistance film 1A without sacrifice of signal response. The carrier selective high resistance film 1A prevents surface resistance of an amorphous semiconductor thick film 1 from lowering and since creeping discharge due to a bias voltage can be suppressed by surrounding the voltage applying electrode 2 with the region 2A formed with no electrode thereby ensuring a sufficient creeping breakdown voltage, a sufficient detection sensitivity can be attained by applying a high bias voltage to the voltage applying electrode 2.

Abstract: 본 발명은 시클로카보네이트 올리고머와 아민 올리고머를 가교결합시켜 형성된 혼성 비이소시아네이트 폴리우레탄 네트워크 폴리머에 관계한다. 시클로카보네이트 올리고머는 복수의 말단 시클로카보네이트기를 포함한다. 시클로카보네이트 올리고머는 4 내지 12중량%의 말단 에폭시기를 포함한다. 시클로카보네이트 올리고머는 시클로카보네이트기와 에폭시기를 포함하므로 형성된 네트워크를 혼성 비이소시아네이트 폴리우레탄 네트워크라 부른다. 시클로카보네이트 올리고머는 일차 아민에 대해 2.0 내지 5.44의 평균 공유결합형성도를 가진다. 아민 올리고머는 일차 아민-말단 올리고머를 포함하고 시클로카보네이트기에 대해 3.0 내지 3.8의 평균 공유결합형성도를 갖는다. 아민 올리고머는 시클로카보네이트 올리고머의 시클로카보네이트기에 대한 아민 올리고머의 일차 아민기간의 화학양론적 비율을 달성하는데 필요한 아민 올리고머의 양의 0.93 내지 0.99의 양으로 존재한다. 형성된 혼성 비이소시아네이트 폴리우레탄 네트워크 폴리머는 0.96중량비 이상의 겔비율을 가진다. 본 발명은 또한 비이소시아네이트 폴리우레탄 네트워크 제조방법과 복합재료 매트릭스로서의 용도에도 관계한다.
