摘要:
For thin insulating layers the observation of a linearI‐Vcurves is often cited asprima facieevidence that the carriers originate from thermal bulk generation. In the present paper we point out that a linearI‐Vcurve can also arise from an emission‐limited or contact‐controlled current. We present an unambiguous experimental criterion to determine whether a linearI‐Vcurve results from contact emission or bulk generation.
