Interfacing Solution-Grown C-60 and (3-Pyrrolinium)(CdCl3) Single Crystals for High-Mobility Transistor-Based Memory Devices
Aligned ferroelectric single crystals of (3-pyrrolinium)(CdCl3) can be prepared from solution on top of aligned semiconducting C-60 single crystals using an orthogonal solvent. Memory devices based on these ferroelectric/semiconductor bilayered heterojunctions exhibit much larger hysteresis compared with that of only C-60 single crystals. More importantly, the introduction of the ferroelectric layer induces the memory window without dramatically reducing the charge mobility.
