Faster and More Efficient Electronics
The development from the Nanoelectronics Device Laboratory (Nanolab), in collaboration with Microsystems Laboratory, focuses on a distinct combination of materials leading to brain-inspired functions and advanced electronic switches, consisting of the standout unfavorable capacitance Tunnel Field-Effect Transistor (TFET).
Worldwide of electronic devices, a transistor or “switch” can be compared to a light switch, determining whether current circulations (on) or does not (off). These are the famous ones and 0s of binary computer system language, and this basic action of switching on and off is integral to nearly every function of our electronic gadgets, from processing information to keeping memory.
The TFET is an unique type of switch designed with an energy-conscious future in mind. Unlike conventional transistors that require a specific minimum voltage to switch on, TFETs can operate at considerably lower voltages. This enhanced design means they consume significantly less energy when switching, thus significantly lowering the general power usage of gadgets they are incorporated into.

According to Professor Adrian Ionescu, head of Nanolab, “Our ventures represent a significant leap forward in the domain of electronic devices, having shattered previous performance standards, and is exemplified by the impressive capabilities of the negative-capacitance tungsten diselenide/tin diselenide TFET and the possibility to create synaptic nerve cell function within the exact same innovation.”
Sadegh Kamaei, a PhD prospect at EPFL, has harnessed the capacity of 2D semiconductors and ferroelectric materials within a completely co-integrated electronic system for the very first time. The 2D semiconductions can be utilized for ultra-efficient digital processors whereas the ferroelectric material supplies the possibility to continuously keep and process memory at the very same time.
Kamaei added, “Working with 2D semiconductors and incorporating them with ferroelectric materials has been challenging yet immensely fulfilling. The prospective applications of our findings might redefine how we view and communicate with electronic gadgets in the future.”
Mixing Traditional Logic With Neuromorphic Circuits
Furthermore, the research dives into creating switches comparable to biological synapses– the detailed ports in between brain cells– for neuromorphic computing. “The research marks the first-ever co-integration of von Neumann logic circuits and neuromorphic functionalities, charting an amazing course toward the production of ingenious computing architectures identified by extremely low power intake and hitherto undiscovered abilities of building neuromorphic functions combined with digital details processing,” adds Ionescu.
Such advances hint at electronic devices that operate in ways parallel to the human brain, marrying computational speed with processing info in a method that is more in line with human cognition. The future may well see devices that are not just smarter and much faster however exponentially more energy-efficient.
