Chemical bonds, including covalent and ionic endow semiconductors with stable electronic configurations but also impose constraints on their synthesis lattice-mismatched heteroepitaxy. Here, the unique multi-scale van der Waals (vdWs) interactions are explored in one-dimensional tellurium (Te) systems to overcome these restrictions, enabled by vdWs bonds between Te atomic chains spontaneous misfit relaxation at quasi-vdWs interfaces. Wafer-scale nanomeshes composed of self-welding nanowires...

Using CMOS-compatible Pd catalysts, we demonstrated the formation of high-mobility ⟨111⟩-oriented GaSb nanowires (NWs) via vapor–solid–solid (VSS) growth by surfactant-assisted chemical vapor deposition through a complementary experimental and theoretical approach. In contrast to NWs formed conventional vapor–liquid–solid (VLS) mechanism, cylindrical-shaped Pd5Ga4 catalytic seeds were present in our Pd-catalyzed VSS-NWs. As solid stoichiometric was found have lowest crystal surface energy...
As an important semiconductor nanomaterial, InP nanowires (NWs) grown with a typical vapor–liquid–solid mechanism are still restricted from their low electron mobility for practical applications. Here, nonpolar-oriented defect-free wurtzite NWs of as high 2000 cm2 V–1 s–1 can be successfully synthesized via Pd-catalyzed vapor–solid–solid growth. Specifically, PdIn catalyst particles involved and found to expose PdIn{210} planes at the nucleation frontier due minimal lattice mismatch nonpolar...

Abstract Perovskite materials are ideal candidates for the activity layers in electrooptic components due to their effective light absorption and high carrier mobility. However, perovskites produced through traditional solution methods often suffer from poor crystallinity defect density susceptible damage under temperature exposure, which limits device performance.

Abstract Negative photoconductivity (NPC) mechanisms are widely investigated for high‐performance InAs nanowire (NW) phototransistors, where these usually attributed to severe carrier scattering centers, light‐assisted hot electron trapping in the surface oxide, and/or defects induced photogating layer. However, further insights into their photodetecting mechanisms, as well corresponding performance enhancement of NW still very limited. This work reports NPC behavior surface‐modified...
