In the past half-century, the semiconductor industry has relied on the scaling of complementary metal-oxide-semiconductor (CMOS) transistor dimensions and on material and geometrical innovations to increase the computational density. Approaching the end of ...

This letter introduces a reconfigurable planar square-coil-shaped inductor exploiting as the tuning mechanism the insulator-to-metal transition (IMT) of a vanadium dioxide (VO2) switch placed in the interwinding space in an unprecedented manner. The VO2 th ...

We propose and experimentally demonstrate double-gated n-type WSe 2 FETs with excellent top gate high-k dielectric layer. Under back gate control, the devices behave as n-type enhancement transistors, with ON/OFF current ratios larger than 6 orders of magn ...

Recently, the field of Metal-Insulator-Transition (MIT) materials has emerged as an unconventional solution for novel energy efficient electronic functions, such as steep slope subthermionic switches, neuromorphic hardware, reconfigurable radiofrequency fu ...

Junctions between n-type semiconductors of different electron affinity show rectification if the junction is abrupt enough. With the advent of 2D materials, we are able to realize thin van der Waals (vdW) heterostructures based on a large diversity of mate ...

We propose and experimentally demonstrate top-gated complementary n- and p-type black phosphorous field effect devices (FETs) by engineering the workfunction of pre-patterned electrodes embedded in a SiO2 bottom layer. Pre-patterned electrodes offer the ad ...

The article presents the design, fabrication and characterization of a novel complementary metal-oxidesemiconductor (CMOS) compatible reconfigurable Ka band bandstop structure using split ring resonators (SRR) while employing the Vanadium Dioxide (VO2) pha ...

In this work we report a new class of ultra-thin film devices based on n-n van der Waals (vdW) heteroj unctions of MoS2 and VO2, which show remarkable tunable characteristics. The favorable band alignment combined with the sharp and clean vdW interface det ...
