Photolithography-Based Micropatterning Integration of Quantum-Dot Electroluminescent Displays with Nonvolatile Charge Trap Memory

Student

Description:

A memory-in-pixel (MIP) is demonstrated using non-volatile charge trap memory with an Al2O3/HfO2/Al2O3 (AHA) structure and integrated quantum dot light-emitting diodes (QD-LED). The AHA structure exhibits high charge trapping capacity, achieving a 4.7 V memory window, Ion/off ratio of 108. The integration of QD-LED enables a self-erasing functionality via the photovoltaic effect without an external light source.
