Japanese Scientists Develop 1-nanometer Semiconductor Nanotubes with Potential for Advanced Electronics

• June 6, 2026

A team of Japanese researchers has successfully fabricated semiconductor nanotubes with diameters near 1 nanometer (nm), marking a significant advancement in nanoscale materials science. These ultra-thin tubes are made from molybdenum disulfide (MoS₂), an inorganic semiconductor, and represent some of the smallest semiconductor nanotubes reported to date.

Advancing Nanotube Technology Beyond Carbon Structures

While carbon nanotubes have dominated the field of nanoscale tubular materials for years, this new development shifts focus towards inorganic semiconductors like MoS₂. The researchers highlighted that the tiny diameter of these MoS₂ nanotubes—about 1 nm, or roughly 100,000 times thinner than a human hair—could offer unique properties suitable for electronics and fundamental quantum studies.

Unlike carbon nanotubes, which primarily exhibit exceptional mechanical and electrical properties without intrinsic semiconductor behavior, MoS₂ nanotubes inherently combine the advantages of semiconducting materials with the nanoscale tubular geometry. This could pave the way for new types of transistor channels, sensors, and other nanoscale electronic components where size reduction and precise control over electronic properties are critical.

Due to their semiconductor nature, these MoS₂ nanotubes may enable the miniaturization of electronic devices beyond the current limits of traditional silicon technology. They could serve as nearly ready-made transistor channels or active components in highly compact circuitry, potentially contributing to the evolution of future electronics toward quantum regimes and ultra-sensitive sensing applications.

The research not only demonstrates the feasibility of growing molybdenum disulfide nanotubes at extremely small diameters but also opens new avenues for exploring the interplay of nanoscale geometry and semiconductor physics. Such structures may find practical use in nanoscale sensors, quantum effect experiments, and novel transistor designs that demand both high performance and miniaturization.

Details regarding commercial viability, integration into existing manufacturing processes, or device-level performance were not provided. However, this achievement underscores the rapidly evolving field of semiconductor nanomaterials and their potential to reshape various technology sectors.

Researchers in Japan have created semiconductor nanotubes made of molybdenum disulfide just 1 nm in diameter, offering promise for next-gen electronics.
