All-organic single-transistor permanent memory device

We present an all-organic permanent memory transistor using an amorphous spin-cast gate insulator. This gate insulator exhibits a remanent polarisation in its amorphous state, a unique property, which is best described as “ferroelectric-like”. The memory transistor thus built perform extremely well, even when compared to inorganic ferroelectric memory transistors; the memory “on” to memory “off” current ratio is close to 3×10-a 4 , while time-dependent studies show retention times of 14 hours and more.
