X-Ray-Induced Bulk Photovoltaic Effect in Insulators

X-Ray-Induced Bulk Photovoltaic Effect in Insulators

When an insulator, sandwiched between metals of dissimilar work functions, is irradiated with x-radiation, a voltage related to the contact potential difference of the metals is observed. This phenomenon, known as the bulk photovoltaic effect, has been demonstrated in a variety of metal-insulator-me...

Zusammenfassung:When an insulator, sandwiched between metals of dissimilar work functions, is irradiated with x-radiation, a voltage related to the contact potential difference of the metals is observed. This phenomenon, known as the bulk photovoltaic effect, has been demonstrated in a variety of metal-insulator-metal combinations. Evidence that the voltage is not generated by junctions, barrier layers, or similar other phenomena is presented.
