Abstract Graphene nanoribbons (GNRs) are narrow strips of graphene with widths ranging from a few nanometers to tens nanometers. GNRs possess most the excellent properties graphene, while also exhibiting unique physical characteristics not found in such as an adjustable band gap and spin-polarized edge states. These make appealing candidate for carbon-based electronics. In this review, we begin by introducing geometry electronic bands GNRs. We then discuss various methods fabricating analyze...
Graphene nanoribbons (GNRs) with widths of a few nanometers are promising candidates for future nanoelectronic applications due to their structurally tunable bandgaps, ultrahigh carrier mobilities, and exceptional stability. However, the direct growth micrometer-long GNRs on insulating substrates, which is essential fabrication devices, remains an immense challenge. Here, epitaxial hexagonal boron nitride (h-BN) substrate through nanoparticle-catalyzed chemical vapor deposition reported....
Two-dimensional (2D) moir\'e superlattices have been extensively investigated, whereas the one-dimensional (1D) remained largely unexplored, due to difficulty in achieving 1D experimentally. Recent theoretical studies predicted that certain collapsed chiral carbon nanotubes (CNTs) behave as with novel strongly correlated physics, owing emergence of flat bands. However, realization bands is limited CNTs a narrow range chirality, which hinders experimental investigation. Here, using molecular...
For applications of single-walled carbon nanotubes (SWNTs) in integrated circuits, it is crucial to have high–tube density arrays SWNTs that are well aligned and purely semiconducting. In this work, we report on the direct growth close-packed SWNT hexagonal boron nitride (hBN) substrates, demonstrating high alignment uniform chirality within each array. Molecular dynamics simulations suggest a self-assembly mechanism resulted from intertube van der Waals attraction ultralow sliding friction...
Nanophotonic circuits are regarded as a transformative technology that can overcome many challenges faced by electronic circuits, particularly concerning operating frequency limits. However, the development of nanophotonic utilizing plasmons is strongly hampered absence fundamental building blocks such long-lived deep-subwavelength plasmons, plasmonic waveguides, and field-effect transistors (FEPTs). Here, we demonstrate Luttinger-liquid FEPTs based on metallic–semiconducting carbon nanotube...
Abstract Graphene nanoribbons (GNRs) and carbon nanotubes (CNTs), two representative one-dimensional (1D) graphitic materials, have attracted tremendous research interests due to their promising applications for future high-performance nanoelectronics. Although various methods been developed fabrication of GNRs or CNTs, a unified method allowing controllable synthesis both them, as well heterojunctions, which could largely benefit nano-electronic applications, is still lacking. Here, we...
Polaritons in two-dimensional (2D) materials have shown their unique capabilities to concentrate light into deep subwavelength scales. Precise control of the excitation and propagation 2D polaritons has remained a central challenge for future on-chip nanophotonic devices circuits. To solve this issue, we exploit Cherenkov radiation, classic physical phenomenon that occurs when charged particle moves at velocity greater than phase medium, low-dimensional material heterostructures. Here,...

Abstract Polaritons in low‐dimensional materials have shown their unique capabilities to concentrate light at the deep subwavelength scale. They behave quite differently from those conventional metals. On one hand, strongly confined polaritons exhibit a large tunability wavelength following different scaling behaviors systems. other they show novel reflection when encounter topographic boundaries or electronic discontinuities. Here, recent progress on and of three representative material...
