The nucleating seed effect of hexagonal boron nitride (h-BN) has been proved to contribute to the single orientation of in-plane h-BN/graphene heterostructures with epitaxial stitching on Ni(111) surfaces, and the growth of h-BN prior to that of graphene is essential to achieve this goal.

A drain-engineered feedback-gate structure is adopted in high-performance carbon-nanotube-film-based field-effect transistors, to cope with the common issue of poor off-state properties and ambipolar behavior. Our results show 2 orders of magnitude reduction in off-current while maintaining 0.2 mS/μm high transconductance, and succesfully meet the 10 nA/μm logic-technology standard-performance power requirement.

Thickness-dependent wrinkling of PDMS films for programmable mechanochromic responses
Zhiwei Li, Yun Liu, Melinda Marin, and Yadong Yin*
University of California, Riverside, USA
This work reveals the thickness dependence of the wrinkling behaviors of plasma-treated polydimethylsiloxane (PDMS) films. For thick films, the wrinkles can be predicted by the classic nonlinear finite mechanics, giving rise to brilliant structural colors. For thin films, the wrinkles are large and random. These observations provide new opportunities for understanding the wrinkling mechanics and have promising applications in smart optical materials.

Suppressed threshold voltage roll-off and ambipolar transport are achieved via feed-back gate (FBG) structure in multilayer transition metal dichalcogenide transistors, where source/drain electrodes extend and overlap with Y2O3 dielectric on top of channel. FBG at source in multilayer MoS2 transistor exhibits neglectable threshold voltage (Vth) roll-off and a low drain-induced-barrier-lowering (DIBL) of 84 mV/V, while FBG at drain in multilayer WSe2 transistor could tailor transport from bipolar to unipolar.
