Studies on sensitivity of porous silicon surfaces to environmental gases

We have studied the electrophysical properties of porous silicon p-n junction in an atmosphere of various gases: moisture, ammonia, benzene, acetone, and ethanol. The high sensitivity of ac conductivity to the polar gas molecules is connected with an additional pathway through the opened surface of...

Zusammenfassung:We have studied the electrophysical properties of porous silicon p-n junction in an atmosphere of various gases: moisture, ammonia, benzene, acetone, and ethanol. The high sensitivity of ac conductivity to the polar gas molecules is connected with an additional pathway through the opened surface of the p-n junction.
