A single-layer micromachined tunable capacitor with an electrically floating plate

Single-electron transport in electrically tunable nanomagnets.

We study a single-electron transistor (SET) based upon a II-VI semiconductor quantum dot doped with a single-Mn ion. We present evidence that this system behaves like a quantum nanomagnet whose total spin and magnetic anisotropy depend dramatically both on the number of carriers and their orbital nature. Thereby, the magnetic properties of the nanomagnet can be controlled electrically. Converse...

Surface micromachined, complementary-metal-oxide-semiconductor compatible tunable capacitor with 14:1 continuous tuning range

A Parallel-plate-based Fishbone-Shape MEMS Tunable Capacitor with Linear Capacitance-Voltage Response

A novel fishbone-shape parallel-plate-based capacitor with high tunability and linear C-V response is presented. The electrodes consist of a set of lateral cantilever beams of different lengths, attached to a longitudinal fixed-fixed beam. An insulating layer prevents contact between the electrodes. When a DC voltage is applied, the longitudinal and lateral beams undergo out-of-plane deformatio...

Design of a Wide Tuning Range Micromachined Tunable Capacitor for Wireless Communications

We present results on the development a new micro electromechanical parallel plate tunable capacitor with a wide tuning range. Different from conventional parallel plate tunable capacitors, this new tunable capacitor consists of one suspended movable top plate and two fixed plates. One fixed plate and the top plate form the variable capacitor, while the other, together with the top plate, is us...

Micromachined tunable metamaterials: a review

This paper reviews micromachined tunable metamaterials, whereby the tuning capabilities are based on the mechanical reconfiguration of the lattice and/or the metamaterial element geometry. The primary focus of this review is the feasibility of the realization of micromachined tunable metamaterials via structure reconfiguration and the current state of the art in the fabrication technologies of ...
