Resumo(s)
Al/LiF/poly(spirofluorene)/Ba/Al diodes submitted to bias
voltages near 15 V undergo a change to a nonvolatile memory known as
electroforming. Prior to electroforming, electron trapping occurs, followed by a
tunneling current due to electrons from the polymer into LiF. At the onset
voltage for electroforming, a sudden electroluminescence burst originating from
electronic excitations in the polymer is detected. This confirms that hole injection
into the polymer through LiF occurs leading to nonvolatile resistive switching.
