## Description

- description: Transistors fabricated from thin-film single crystals of organic semiconductors
    (OSCs) have exhibited high mobility exceeding 10 cm2 V−1 s−1 and show compatibility
    with low-cost solution processing. However, their carrier mobility is limited
    by the molecular vibrations in their soft lattices. This study establishes a practical
    method for applying compressive strain to single-crystal OSCs to enhance mobility
    and transistor performance. In this method, a polymer film substrate is bent to
    mechanically stretch its surface. Organic single-crystal transistors are then
    laminated onto the stretched surface of substrate. Releazing the stretch by recovering
    the flat surface of the substrate allowed the transistors to be compressed by
    up to 3%. This resulted in a 52% increase in mobility, reaching 26.4 cm2 V−1 s−1.
    X-ray diffraction measurements confirmed lattice strain in the OSC single crystals.
    Moreover, carrier mobility and cutoff frequency increased in MHz-operating short-channel
    transistors, demonstrating applicability for high-frequency devices. The mobility
    increase is maintained even three years after introducing the 1% compressive strain,
    possibly owing to the flexible, molecularly thin characteristics of OSC single
    crystals. The proposed strain management methods may provide new avenues to enhance
    the performance of high-mobility and high-frequency electronic devices based on
    OSC thin-film single crystals.
