Summary: This article introduces a reconfigurable carbon nanotube barristor based on a Schottky barrier CNT transistor, which exhibits significant rectifying characteristics and can be reconfigured to different rectifying modes by applying gate voltage. The reconfigurability comes from the ambipolar characteristics of the CNT channel, and the rectification behavior can be attributed to the drain-induced self-gating effect.

Summary: Formation of self-organized nanodiamond ring structures is reported due to dynamical heterogeneity in super undercooled carbon, created by nanosecond laser melting of amorphous carbon layers. Diamond tetrahedra self-organize to lead to the formation of string and ring structures, on which nanodiamonds nucleate and grow. Denser ring structures are formed in Q-carbon due to higher undercooling and enhanced diamond nucleation, showing larger average size and higher growth velocities compared to homogeneous nucleation.

Summary: Gamma irradiation was applied to vertically aligned carbon nanotube (CNT) forests to improve the interfacial adhesion and then spun into CNT yarns. The yarns spun from the irradiated forests showed higher tensile strength and lower breaking elongation. Increasing spinning tension improved the strength of both the irradiated and unirradiated yarns, but the irradiated yarns had more significant improvements. The relative improvements in yarn tenacity ranged from 14% to 26% under various spinning tensions.

The maximum energy conversion efficiency is also greatly improved. Twistron anode and cathode yarn arrays are stretched out-of-phase to double the output voltage.
