Interfacing Solution‐Grown C₆₀ and (3‐Pyrrolinium)(CdCl₃) Single Crystals for High‐Mobility Transistor‐Based Memory Devices

Abstract

Aligned ferroelectric single crystals of (3-pyrrolinium)(CdCl₃ ) can be prepared from solution on top of aligned semiconducting C₆₀ single crystals using an orthogonal solvent. Memory devices based on these ferroelectric/semiconductor bilayered heterojunctions exhibit much larger hysteresis compared with that of only C₆₀ single crystals. More importantly, the introduction of the ferroelectric layer induces the memory window without dramatically reducing the charge mobility.
