New Semiconductor Structure Allows Unhindered Current Flow in 2D Materials
A joint research team from KAIST and Sungkyunkwan University has developed a novel semiconductor structure enabling current to flow without resistance in two-dimensional materials, significantly reducing contact resistance.
A collaborative research team from the Korea Advanced Institute of Science and Technology (KAIST) and Sungkyunkwan University announced the development of a new semiconductor structure that allows electrical current to flow unimpeded in two-dimensional materials. This breakthrough addresses the long-standing "electrical bottleneck" in chip manufacturing and is expected to substantially lower contact resistance in next-generation semiconductor devices.
The new structure utilizes a single-layer, atom-thick two-dimensional material, ", which features continuous semi-metallic and semiconducting regions within the same material. This design facilitates the seamless passage of current across boundaries without significant resistance. Researchers were able to directly observe this charge transport at the nanoscale using atomic force microscopy.
This development is crucial as contact resistance has become a major impediment to creating smaller and more energy-efficient semiconductors. Two-dimensional materials like ", are considered promising for future technologies, including AI, data centers, and wearable devices, as traditional silicon technology approaches its physical limits.
The findings, published in the journal ", demonstrate the potential of this new structure to enhance the performance and efficiency of semiconductor devices, offering key support for future computational advancements.
