Abstract

Advanced device structures are proposed for high-performance polymeric light emitting diodes based on the ferroelectric, pyroelectric, and piezoelectric properties of the very thin crystalline Langmuir-Blodgett films of P(VDF-TrFE). This ferroelectric incorporated polymeric light emitting diode structure has a capability to lower the barrier height for efficient carrier injection and modulate the balance of the carriers for enhanced quantum efficiency. The barrier height can be reduced up to 1 eV while the tunneling barrier width can be modulated up to 8&percent;. This can be achievable only using the crystalline thin films of P(VDF-TrFE).
