Butterfly-Inspired 2D Periodic Tapered-Staggered Subwavelength Gratings Designed Based on Finite Difference Time Domain Method
Published 2015“…The butterfly-inspired 2D periodic tapered-staggered subwavelength gratings were developed mainly using finite difference time domain (FDTD) method, assisted by using focused ion beam (FIB) nanoscale machining or fabrication. The periodic subwavelength structures along the ridges of the designed gratings may change the electric field intensity distribution and weaken the surface reflection. …”

3D printing of high frequencies ultrasound angle probe wedges
Published 2024“…As a result, the author of this project will look into creating the 45° and 60° wedges via 3D printing and joining them with a 90° transducer to create an angle beam transducer. This is being done in an effort to lower production costs and facilitate the fabrication of the angle probe wedge. …”

Solution processed transition metal oxides selective contacts for Si heterojunction solar cells
Published 2021“…In this work, we have first prepared hole selective contacts using solution processed MoOx (s-MoOx) by spin-coating and physical evaporated MoOx (e-MoOx) by electron beam evaporator. The performance of the s-MoOx/Si HSC has been investigated and optimized, which has been demonstrated solar cell efficiency of 12.5% for s-MoOx/Si HSC that is comparable to efficiency of 13.3% for e-MoOx/Si HSC. …”

Tunable Mechanical Response of Self-Assembled Nanoparticle Superlattices
Published 2024“…Here, we perform in situ nanomechanical experiments that evidence up to an 11-fold increase in stiffness (∼1.49 to 16.9 GPa) and a 5-fold increase in strength (∼88 to 426 MPa) because of surface stiffening/strengthening from shaping these nanomaterials via focused-ion-beam milling. To predict the mechanical properties of shaped NPSLs, we present discrete element method (DEM) simulations and an analytical core-shell model that capture the FIB-induced stiffening response. …”
