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. …”

Materials beyond monolayers: The magnetic quasi-1D semiconductor CrSBr
Published 2024“…We discuss the stability of CrSBr in air and show atomic scale structural manipulation through electron beam-driven transformations. We conclude that the stability and structural amenability of CrSBr provide opportunities for imagining devices that use bulk crystals yet exploit unique magnetic and quantum confinement effects.…”

Study of a 1 eV GaNAsSb photovoltaic cell grown on a silicon substrate
Published 2014“…We report the performance of a 1 eV GaNAsSb photovoltaic cell grown on a Si substrate with a SiGe graded buffer grown using molecular beam epitaxy. For comparison, the performance of a similar 1 eV GaN0.018As0.897 Sb 0.085 photovoltaic cell grown on a GaAs substrate was also reported. …”

Three dimensional acoustic tweezers with vortex streaming
Published 2021“…Acoustic tweezers based on single-beam focused acoustic vortices have attracted considerable attention due to their selective trapping capability, but have proven difficult to use for three-dimensional (3D) trapping without a complex transducer array and significant constraints on the trapped particle properties. …”

Small-scale wind energy harvesting using piezoelectric materials
Published 2015“…A two degree-of-freedom galloping piezoelectric energy harvester (GPEH) is proposed which successfully enhances the output power in low wind speeds. A beam stiffener is employed as an electromechanical coupling magnifier, which is proved to be an easy but greatly effective efficiency enhancing method for energy harvesting from VIV, flutter as well as galloping. …”
