[발명의 상세한 설명]
[산업상 이용분야]
본 발명은 광전도 소자에 관한 것이다. 본 발명은 테트라포트(tetrapod)형상의 산화 아연 위스커(whisker)로 되어 있는 고감도의 새로운 광전도 소자에 관한 것이다. 본 발명의 광전도 소자는 여러가지용도, 예를 들어, 자외선 검출소자, 소형 모우터의 속도 제어, 음질조정, 혈액 맥파(맥파(脈波)측정등에 사용된다.
[종래의 기술]
종래의 관전도 소자는 CdS를 당결정 형태로 사용하거나 증착 박막(蒸着薄膜)형태로 사용할 수 있으나, 거의가 소결체 형태로 하여 광범위하게 사용했다. CdS외에도 ZdS, CdSe, GaAs, Si, Ge, pdS, InSb, Se, CdTe, PdSe, PdTe, Sb2S3PbO 및 ZnO 등을 사용하고 있다. 광전도성을 향상시키기 위하여 Ag, Cl, Ca, 또는 Sb,등을 물질에 참가고 있다.
광을 장시간 조사(照射)하면, 종래의 광전도 소자는 열화(劣化)되어 이의 그 저항이 변하며, 따라서 종래의 광천도 소자는 신뢰성이 나쁘다는 문제점 있다.
더욱이, 높은 광감응성을 가진 광전도 소자가 널리 요망되었다.
[발명의 개시(開示)]
본 발명에서는 코어부(core)와, 이 코어부로 부터 각기 상이한 4축방향으로 연장된 4개의 침상(針狀)결정부터 각각 구성되어 있는 테트라포트 형상의 산화 아연 위스커를 접합시켜 광전도 소자의 수광부(手光部 : photodetector section)를 구성한다. 산화 아연 위스커의 예는 제1도와 제2도에 각각 나와 있다.
침상 결정부의 기부(基部)의 직경이 0.7∼14㎛이고, 침상 결정부의 기부로부터 첨단부까지의 길이가 3∼200㎛ 이때 우수한 효과를 얻는다.
본 발명의 관전도 소자는 X-선 회절에 의하여 확인되는 침상의 산화 아연단결정의 집합체로 되어 있기 때문에, 이는 극히 고감도이고 거의 열화(劣化)되지 않는다.
또한, 테트라포드 형상의 산화 아연 위스커를 집합하고 있기 때문에, 그 집합체는 공기율(porosity)이 크다. 더욱이, 산화 아연 위스커는 투명한 단결정체이므로 광을 소자의 깊은 부분까지 들어가고 흩어지지 않으므로 쉽사리 입사하고 산란되는 일은 거의 없다. 따라서, 고감도의 광전도 소자를 얻을 수 있을 것이다.
[발명의 바람직한 실시태양]
본 발명의 실시예를 구체적으로 설명한다.
[실시예 1]
입도 분포가 5∼50㎛인 금속 아연 분말(100g을 물의 존재하에 모르타르 (mortar)형 분쇄기로 분쇄하고 물속에서 3일간 방치하였다. 이들 처리를 20℃에서 실시하였다. 건조후, 분말을 알루미나로 만든 도가니에 넣고 100℃로 유지되는 로에서 1시간 동안 가열하여 테트라포트 형상의 산화 아연 위스커를 얻었다. 수득한 침상 결정체는 기부의 편균 직경이 8㎛이었고 기부로 부터 첨단부까지의 평균 길이가 50㎛이었다. 위스커는 대부분이 각기 상이한 4축 방향으로 침상 결정이 뻗어나간 테트라포트 형상을 나타내었으나, 1축 방향, 2축 방향 및 3축 방향으로 뻗어나간 위스커가 약간 혼입되어 있었는데, 이것은 위스커 일부가 파괴된데 기인하는 것이라고 생각된다.
소량의 위스커를 유리판(1)과 석영 유리판(3)사이에 샌드위치하고 500g/㎠의 압력으로 프레스하여 두께가 약 20㎛되게 하였다.(제3도와 제4도 참조). 이들 도면에서 (2)와 (2')는 알루미늄으로 부터 유리판(1)에 형성된 한쌍의 병렬형 전극(tandem typr tlectrode)을 나타내고, (4)는 테트라포드 형상 산화 아연 위스커를 나타내다. 이어서, 150g /㎠의 압력을 가하여 수광부를 형성하였다. 제조된 광전도 소자에300룩스 (lux)의 광을 조사하는데, 이때 인가 전압을 제어하여 사용된 에너지를 항상 300mW가 되도록 유지하였다. 이와 같은 조건하에서광전도 소자를 1000시간 동안 계속유지하였다. 이 시간 동안 1룩스(lux)에 서의 소자의 광휘 저항의 변화를 임의 간격로 모니터링하였다. 그 결과를 제5도에 나타내었다.
비교하기 위하여 CdS 소결체와 ZnO 소결체로 되어 있는 광전도 소자의 광휘 저항의 변화를 모니터링하여 그 결과를 나타내었다.
본 발명의 광전도 소자는 고감도이어서 그 저항치는 0.1∼1000룩스의 조도(照度)변화에서 세자리 이상으로 크게 변화하였다.
[실시예 2]
실시예 1에서 사용한 것과 동일한 테트라포드 형상의 산화 아연 위스커에 Cu를 0.1원자 %첨가하여 혼합하고 900℃에서 소결한 다음, 소결체에 In을 진공 증착시켜서 전극을 구성한다. 제조된 소자를 부하 수명시험(load lifetime test)을 한 결과, 소자는 실시예 1과 같은 양호한 특성을 나타내었고, 저항 변화율은 1000시간 후 12%이었다. 이 소자는 고감도이어서 그 저항은 0.01∼1000룩스의 조도 변화에서 이상으로 크게 변화하였다.
[실시예 3]
기부의 평균 직경이 0.7㎛ 이하이고, 기부로 부터 첨단부까지의 평균 길이가 3㎛이하인 미소한 테트라포드 형상의 위스커를 사용한 것을 제외하고는 실시예 1과 동일한 방법으로 소자를 제조하고 그 성질을 평가하였다. 소자의 감도는 칫수에서 급격히 감소하였고, 저항치 변화는 두자리수 까지 감소하였다.
[비교예 2]
약 1㎛의 입자 크기를 가진 일반 시약급의 산화 아연 분말(일본국의 關東化學社 제품)을 사용한 것을 제외하고는 실시예 1과 동일한 방법으로 소자를 제조한 결과, 이 소자는 광감응성을 전혀 나타내지 않았으므로 본 발명의 소자와는 비교를 할 수 없었다.
상기 실시예들에 있어서, 테트라포드 형상의 위스커는 비교적 균일한 크기를 가지며, 균일한 크기 분포를 가진 테트라이포트 형상의 위스커는 동일한 특성을 가진 광전도성 소자를 제조할 수 있다록 한다.
전극 재료로서는 주석, 아연, 금, 은, 구리, 철 니켈, 크롬, 코발트, 리튬, 베릴륨, 나트륨, 마그네슘, 티타늄, 바나듐, 망간, 칼륨, 안티몬, 인듐, 카트뮴, 팔라듐, 로듐, 루테늄, 테크네늄, 몰리브덴, 니오븀, 지르코늄, 스트론튬, 루비듐, 칼륨, 아스타틴, 몰로늄, 비스무트, 납, 탈륨, 수은, 배금, 이리듐, 오스뮴, 레늄, 텅그스텐, 탄탈륨, 하프늄, 바륨, 세슘, 프린슘, 라듐, 란탄과 라탄계 원소, 악티늄과 악티늄계 원소 및 이들의 합금과 혼합물이 있다.
테트라포드, 형상의 산화 아연의 성질을 개선시키기 위하여, 은, 구리, 염소, 갈륨, 안티몸과, 때에 따라서는 상시 전극 재료를 포함하여 이들중 한가지 또는 여러가지를 소량 첨가할 수 있다. 첨부량은 한 종류의 첨가물일 때는 0∼10원자 %의 범위에서 첨가하고, 특히 0.005∼0.5원자%가 유효하며, 과량 첨가는 암전류(暗電流)를 증가시키고 소자의 수명을 단축시키게 된다.
또한, 다른 광전도 물질을 테트라포드 형상의 산화 아연 위스커와 함께 사용하여 소자의 특성을 개량할 수 있다.
테트라포드 형상의 산화 아연 위스커의 저항은 알루미늄 또는 리튬을 첨가하거나 또는 도우핑하여 변화시킬 수 있다.
전극은 산화 주석, 산화 이듐, 금 등의 투명한 전도막으로 된 샌트위치형, 평면형, 병렬형 및 적층형 적층령 등과 같은 형태로 할 수 있다.
수광면(photodetecting surface)으로서는 매우 작은 면적에서 큰 면적까지 사용할 수 있고, 본 발명의 광전도 소자는 어떠한 형상으로 할 수 있고, 임의의 삼차원적인 불규칙성을 가진 광전도 소자를 제공할 수 있다.
더욱이, 테트라포드형 침상 결정체의 기부에서 부터 첨단부까지의 길이가 3∼200㎛일때 위스커는 고감도와 안정한 광전도성을 나타낸다.
그러나, 이 길이는 상기 범위로 제한되는 것은 아니다. 바람직하게는 이 길이가. 특성, 위스커의 안정성, 취급용이와 가격면에서, 보아 50∼150㎛일때이다.
침상 결정체의 기부 직경이 0.7∼14㎛일 때, 위스커는 고감도와 안정한 관전도성을 나타낸다. 그러나, 이 직경은 상기 범위로 한정되는 것은 아니다. 바람직하기로는 이 직경이, 특성, 위스커의 안정성, 취급용이와 가격면에서 보아 2∼10㎛일 때이다.
구광부의 두께는, 감도, 바이어스 전압과 소자의 사용 목적에 따라 설계 된다. 더욱이 수광부의 두께는 성형 프레스 압력에 따르고, 성형 프레스 압력을 테트라포드 형상의 위스커가 완전히 파괴되지 않는 범위에서 조정된다.
본 발명의 광전도 소자는 테트라포드 형상의 산화 아연 위스커 단결정을 집합시켜서 된 것이기 때문에, 이는 고감도이고 신뢰성이 높다.
