[HTML][HTML] Enhancing hole injection by electric dipoles for efficient blue InP QLEDs
The unbalanced carrier injection is a key factor that deteriorates the performance of blue InP
quantum dot light-emitting diodes (QLEDs). Therefore, to achieve efficient blue InP QLEDs,
an effective strategy that balances carrier injection through enhancing the hole injection and
transport is in demand. In this study, we introduced an ultrathin MoO 3 electric dipole layer
between the hole injection layer and the hole transport layer (HTL) to form a pair of dipole-
induced built-in electric fields with forward resultant direction to enhance hole injection and …
