Article Abstract

We report for the first time the fabrication of p-type SiC nanowire field-effect transistors (FETs) using an individual Al-doped 3C-SiC nanowire with a single crystalline structure. The Raman spectroscopy of the as-grown p-type wire indicates that the linewidth and peak intensity of LO-phonon bands are sensitive to temperature variations.

Impact of Doping on Cross-Sectional Stress Assessment of 3C-SiC/Si Heteroepitaxy.

Materials (Basel)

May 2023

Consiglio Nazionale delle Ricerche, Istituto per la Microelettronica e Microsistemi (CNR-IMM), Ottava Strada n.5, 95121 Catania, Italy.

In this paper, we used micro-Raman spectroscopy in cross-section to investigate the effect of different doping on the distribution of stress in the silicon substrate and the grown 3C-SiC film. The 3C-SiC films with a thickness up to 10 μm were grown on Si (100) substrates in a horizontal hot-wall chemical vapor deposition (CVD) reactor. To quantify the influence of doping on the stress distribution, samples were non-intentionally doped (NID, dopant incorporation below 10 cm), strongly n-type doped ([N] > 10 cm), or strongly p-type doped ([Al] > 10 cm).

Surface-potential-modulated piezoresistive effect of core-shell 3C-SiC nanowires.

Nanotechnology

September 2022

Department of Mechanical Engineering, Graduate School of Engineering, Kobe University, Kobe, Japan.

The effect of surface potential on the carrier mobility and piezoresistance of core-shell silicon carbide nanowires (SiC NWs) was investigated to realize small and sensitive SiC-microelectromechanical systems sensors. The p-type cubic crystalline SiC (3C-SiC) NWs were synthesized via the vapor-liquid-solid method and coated with silicon dioxide (SiO) or aluminum oxide (AlO) dielectric shells to form core-shell structured NWs with different surface potentials. Four-point bending devices (FBDs) with a field-effect transistor (FET) configuration integrating a single core-shell 3C-SiC NW as the FET channel were fabricated to apply an additional electric field and strain to the core-shell 3C-SiC NWs.

One of the main issues with micron-sized intracortical neural interfaces (INIs) is their long-term reliability, with one major factor stemming from the material failure caused by the heterogeneous integration of multiple materials used to realize the implant. Single crystalline cubic silicon carbide (3C-SiC) is a semiconductor material that has been long recognized for its mechanical robustness and chemical inertness. It has the benefit of demonstrated biocompatibility, which makes it a promising candidate for chronically-stable, implantable INIs.
