Negative Capacitance as Universal Digital and Analog Performance Booster for Complementary MOS Transistors

Christian Enz, Igor Stolichnov, Mihai Adrian Ionescu, Farzan Jazaeri, Ali Saeidi

Boltzmann electron energy distribution poses a fundamental limit to lowering the energy dissipation of conventional MOS devices, a minimum increase of the gate voltage, i.e. 60 mV, is required for a 10-fold increase in drain-to-source current at 300 K. Neg ...

Exploration of Negative Capacitance Devices and Technologies

Ali Saeidi

Conventional device scaling has been the main guiding principle of the MOS device engineering over these past years. However, this aggressive scaling would be eventually limited due to the inability to remove the heat generated by MOSFET devices. The power ...

On the Dynamic Performance of Laterally Gated Transistors

Elison de Nazareth Matioli, Giovanni Santoruvo, Armin Jafari, Catherine Erine, Mohammad Samizadeh Nikooytabalvandani

Laterally gated transistors have been proposed as an innovative device architecture in which a semiconducting channel is controlled by side gates. In this sense, the gate can either be in contact with the sidewalls or be separated by a gap. In the latter c ...

Statics and dynamics of multivalley charge density waves in Sb (111)

Daniele Dragoni, Davide Campi

Charge density waves (CDWs), periodic modulations of the charge density, are among the most abundant and non-trivial ordered phases in condensed matter. Here we demonstrate the occurrence of multi-valley charge density waves (MV-CDW) on the semimetal Sb(11 ...

Development of graphene-based ionizing radiation sensors

Davide Forti, Giovanni Borghi, Alberto Ciarrocchi

We present the first steps to develop radiation sensors based on the graphene field effect transistor technology. Such a sensor exploits the ambipolar behavior of graphene near its Dirac point and it is not dependent on collecting charges, but it senses io ...
