In what might be claimed as an attempt to manifest the potential opportunities of carbon nanotubes market in the next generation electronics space, Skoltech scholars, in conjunction with the research team of IBM Watson Research Center, have recently elucidated the behavior of electrical contacts in carbon semiconductor nanotubes.
For the uninitiated, tech giants today have been proactively investing in research activities to bring forth a viable alternative for silicon that could be used in future electronics applications. In this regard, the principal challenge, as claimed by experts, is contact resistance, which apparently is less prominent in carbon nanotubes – in fact, theoretically, experts say that the channel resistance in carbon nanotubes is better when compared with silicon nanotubes. In response to this fact, carbon nanotubes market players have been constantly dealing with its inbuilt property of increasing the contact resistance when the tube size gets reduced to several tenths of a nanometer, cite sources.
Speaking of the latest research, one of the spokespersons of Skoltech stated that semiconductor tubes that are flattened by metal contacts become metallic, in which case, the contact resistance increases and does not decrease with time. Skoltech’s experts hence claim that this is due to disruption of the axial symmetry of the deformed tube under the metal contact.
As per reliable sources, the Skoltech-led team has thrown light on the steps that might be taken to address the issue of reducing the contact resistance. If expert opinions are to be believed, this insightful research, in all probability, would leave quite an impact in carbon nanotubes market.
Reportedly, through this research, these scholars have come down to a conclusion that it is preferable to use small diameter tubes for manufacturing transistors. Metals with a low surface tension can also be one of the solutions to this critical issue, cite experts.
