Nanostructuring lithium niobate substrates by focused ion beam milling
, 2005 We report on two novel ways for patterning Lithium Niobate (LN) at submicronic scale by means of focused ion beam (FIB) bombardment. The first method consists of direct FIB milling on LiNbO3 and the second one is a combination of FIB milling on a ...

Advanced Functional Materials, EarlyView.The hidden role of Cd segregation at grain boundaries is revealed in p‐type Mg3Sb2 by atom probe tomography and other advanced characterizations. Grain boundary Cd enrichment suppresses the SbMg+ hole‐killer formation and lowers potential barriers, enhancing electrical conductivity.

Silicon Deep Reactive Ion Etching with aluminum hard mask
Materials Research Express, 2019 Silicon Deep Reactive Ion Etching (DRIE) process using a multi-layer mask containing a sputtered Aluminum thin film is studied. Aluminum is a candidate for very high aspect ratio DRIE, due to tis very low etch rate, but its adoption is hindered by the presence of micromasking.

Curvature‐Tuned Friction at Electrified Ionic Liquid Interfaces
Advanced Functional Materials, EarlyView.Graphene curvature plays a key role in friction electrotunability at single‐asperity contacts lubricated by ionic liquids. A 9 nm radius yields stronger tunability than larger radii, with distinct friction coefficients at low and high loads indicating a shift in the slippage plane.

MEMS Inertial Switch for Military Applications
Proceedings, 2017 We developed a MEMS inertial switch (hereafter, the switch) for an ignition system of missiles. The developed switch consists of four folded beams and a plate suspended by the beams, analogous to a well-known spring-mass system.
