Abstract

The cross effect between an ion flux and an electronic current in a nonstoichiometric binary oxide, $A_{1-\delta}O_\mu$, has been analyzed in the light of irreversible thermodynamics. It has been shown that a net flux of the mobile cation vacancy is induced through the system in an electrical potential gradient applied across a pair of the reversible electrodes, which makes the Fick frame shift relative to the laboratory frame. As a consequence, the relative shift is a measure of the effective charge responsible for the cross effect. Two experiments are proposed to measure the shift.

전자 전도체 이온 결합 화합물, $A_{1-\delta}O_\mu$에서 전자의 흐름과 이온의 흐름 사이에서 일어나는 간섭 현상을 비가역 열역학적으로 분석하였다. 이 계를 가역 전극 사이에 두고 전기를 흘리면 주된 전하 나르게인 전자의 흐름에 의하여 잘 움직이는 양이온 빈자리들의 알짜 흐름이 유발되며, 이 반자리의 흐름은 Fick 좌표계를 실험실 좌표계에 대하여 상대적으로 움직이게 한다는 것이 드러났다. 따라서 이 상대속도는 전자와 이온의 흐름간 간섭효과의 크기와 방향을 결정하는 양이온 유효전하의 척도가 되는 것이다. 이 상대속도를 측정하는 두 가지의 실험을 고안하였다.
