Today's world of electronics becomes more and more digital and therefore CMOS becomes the dominant technology. A CMOS process compared to a bipolar process offers several advantages, mainly a low power consumption which is important for portable systems po ...
Spin-dependent ballistic transport in a mesoscopic two-dimensional electron system with two metallic ferromagnetic electrodes is studied using the Landauer-Büttiker formalism. Our calculations predict a pronounced spin-valve effect in the ballistic regime ...

In this letter, we present normally-off GaN-on-Si MOSFETs based on the combination of tri-gate with a short barrier recess to yield a large positive threshold voltage (VTH), while maintaining a low specific on resistance (RON,SP) and high current density ( ...

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 ...
The influences of trapped charges on carrier transport in carbon nanotubes (CNTs) are studied using CNT field-effect transistors with a partial top-gate and a global back-gate. Trapped charges induced by the global back-gate voltage sweeping (+/- 20 V) pro ...
An analytical model for the suspended-gate field-effect transistor (SGFET), dedicated to the dc analysis of SGFET logic circuits, is developed. The model is based on the depletion approximation and expresses the pull-in voltage, the pull-out voltage, and t ...

This work reports on the physical definition and extraction of threshold voltage in Tunnel FETs based on numerical simulation data. It is shown that the Tunnel FET has the outstanding property of having two threshold voltages: one in terms of gate voltage, ...

This work reports on the analysis of high voltage lateral devices. Two different architectures, self-aligned LDMOS and non-self-aligned XDMOS are presented and used in this work. For the separation of the physical effects that take place inside the HV devi ...
We present measurements on a superconducting single-electron transistor (SET) in which the metallic tip of a low-temperature scanning force microscope is used as a movable gate. We characterize the SET through charge stability diagram measurements and comp ...
