Organic
single crystals manifest the intrinsic physical properties of materials.
However, traditional growth of organic single crystals is limited
by low solubility from solutions or complexity from physical vapor
deposition. Here we report a new method to grow organic single crystals
by microspacing in-air sublimation, which avoids costly vacuum system
and time-consuming procedures and is practical for a wide range of
organic crystals. In situ crystal growth observation revealed an unprecedented
vapor-to-melt-to-crystal mechanism, resulting from the micrometer
scale spacing distance between the source and the growth position.
FET devices based on the rubrene crystals directly grown on Si/SiO<sub>2</sub> substrate exhibited higher mobility than the best record
using SiO<sub>2</sub> as the gate dielectric. This effective organic
crystal growth technique can be affordable and handled for almost
every lab, which may be beneficial for future research and application
of organic crystals.
