Paper accepted at Electronics Journal

The paper entitled “Fault Modeling of Graphene Nanoribbon FET Logic Circuits”, written by D. Gil-Tomàs, J. Gracia-Morán, L.J. Saiz-Adalid and P.J. Gil-Vicente has been accepted for publication at Electronics Journal.


Due to the increasing defect rates in highly scaled complementary metal–oxide–semiconductor (CMOS) devices, and the emergence of alternative nanotechnology devices, reliability challenges are of growing importance. Understanding and controlling the fault mechanisms associated with new materials and structures for both transistors and interconnection is a key issue in novel nanodevices. The graphene nanoribbon field-effect transistor (GNR FET) has revealed itself as a promising technology to design emerging research logic circuits, because of its outstanding potential speed and power properties. This work presents a study of fault causes, mechanisms, and models at the device level, as well as their impact on logic circuits based on GNR FETs. From a literature review of fault causes and mechanisms, fault propagation was analyzed, and fault models were derived for device and logic circuit levels. This study may be helpful for the prevention of faults in the design process of graphene nanodevices. In addition, it can help in the design and evaluation of defect- and fault-tolerant nanoarchitectures based on graphene circuits. Results are compared with other emerging devices, such as carbon nanotube (CNT) FET and nanowire (NW) FET.


DSN 2020 will be held at UPV

The Fault Tolerant Systems Group (STF) of the Institute ITACA from the UPV will host the next International Conference on Dependable Systems and Networks (DSN), that will be held in Valencia in June 2020.

Over the years, the International Conference on Dependable Systems and Networks has pioneered the fusion between dependability and security research, understanding the need to simultaneously fight against accidental faults, intentional cyber-attacks, design errors, and unexpected operating conditions. These concerns can no longer be tackled in isolation, neither in general IT nor in internet-of-things, cyber-physical systems, autonomous transportation, robotics and application areas.

We hope to see you in Valencia!!
