A new type of 300 millimeter wafer with semiconductor chips of the semiconductor German manufacturer Bosch are seen in Dresden, eastern Germany on May 31, 2021.
While silicon has swiftly become an integral component of numerous contemporary devices, ranging from smartphones and automobiles to computers and smart homes, scientists have begun to acknowledge that it is nearing the confines of its inherent capabilities.
These limitations are primarily rooted in the atomic structure of silicon, prompting researchers to explore alternative materials and technologies. The vibrational motion of any material generates quantum particles referred to as phonons.
These phonons play a pivotal role in scattering excitons, which encompass electrons or electron pairs responsible for carrying energy and information within electronic devices.
This process unfolds with remarkable speed, covering nanometer-scale distances in femtoseconds. However, a side effect of this rapid transmission is the generation of heat, resulting in energy dissipation and introducing restrictions on the transfer speeds of information.
This highlights the challenges researchers face as they strive to overcome these limitations. In the Re6Se8Cl2 material, a notable phenomenon occurs wherein phonons, instead of scattering excitons, unite with them to generate a novel class of quasiparticles, termed acoustic exciton-polarons.
While polarons have been previously observed in other materials, what sets Re6Se8Cl2 apart is the extraordinary manner in which its polarons move - in a ballistic or scatter-free fashion. This unique characteristic enables them to traverse distances more swiftly, facilitating accelerated information transfer and minimizing heat-related data loss.
In the experiments conducted by the researchers, EurekAlert reported that these polarons demonstrated remarkable agility, moving at twice the speed of electrons in silicon, covering several microns within a nanosecond.
Given that a polaron has a lifespan of approximately 11 nanoseconds, researchers are optimistic about its potential to travel distances exceeding 25 micrometers. This pioneering discovery holds promise for revolutionizing information transfer capabilities in semiconductor technology.

Exhibiting a Comparably Slow Place
Re6Se8Cl2 features excitons that exhibit a comparably slow pace, facilitating their interaction with phonons more readily than their fast-moving counterparts found in other semiconductor materials. This unique dynamic gives rise to polarons capable of moving unobstructed within the material.
Importantly, as quasiparticles respond to light, it opens the door to theoretically achieving processing speeds in the femtosecond range, a remarkable six orders of magnitude faster than contemporary electronics.
Re6Se8Cl2 is distinguished as a super atomic semiconductor, a title earned during its laboratory synthesis. Here, the constituent atoms of the elements involved cluster together to emulate a large atom rather than self-arranging into molecules, marking a significant departure from conventional semiconductor structures.
This innovation holds substantial promise for the future of semiconductor technology. The Re6Se8Cl2 can be fabricated into ultrathin atomic layers, allowing for potential integration with other materials.
Nevertheless, the scarcity and exorbitant cost of the initial element, Rhenium, render it an impractical choice for commonplace devices in the foreseeable future.
With their sights set on the prestigious journal Science, the research team remains optimistic about discovering alternative semiconductors capable of surpassing the performance of Re6Se8Cl2.
