Scientific Background:

Over the last decades, following Moore's law, the continuous downscaling of the Si based, planar integrated circuit technology has been the main driving force to increase switching speed and reduce power consumption as well as cost of ultra-scaled integrated circuits. However, challenges arising from implications of short-channel effects forced a shift of research efforts towards the integration of new materials, processes and device architectures. In this context, emerging distributed computing paradigms such as the Internet of Things (IoT) are placing extraordinarily stringent constraints on computing hardware performance that require both a beyond CMOS and "More than Moore" approach enabling efficient and low-power technologies for data-intensive tasks such as Artificial Intelligence (AI) algorithms. Consequently, there is a significantly growing need for functional diversification as well as alternative computing and memory devices.

Mission Statement:

In the quest to push the contemporary scientific boundaries in nanoelectronics, the Weber group is focusing on a "More than Moore" approach extending device performances beyond the limits imposed by transistor miniaturization, enabling next generation energy efficient reconfigurable integrated circuits, targeting low supply voltages and a reduction of transistor count. Moreover, novel devices that fuse computing with non-volatile memory functionality are being conceived and advanced towards circuit enablement.
