Thermophysical Properties of Ni Films for LIGA Microsystems
Diana-Andra Borca-Tasciuc,Rajesh Nimbalkar,Gang Chen,Gang Chen,Samuel Graham,Theodorian Borca-Tasciuc +5 more
TL;DR: In this paper, temperature dependent thermophysical properties characterization of electrodeposited Ni and NiMn alloys intended for LIGA Microsystems applications are reported, which are correlated with scanning electron microscopy studies of the grain structure and measurements of the electrical transport properties.
Proceedings ArticleDOI
Mechanical Deformation Study of Flexible Leadset Components for Electromechanical Reliability of Wearable Electrocardiogram Sensors
Benjamin G. Stewart,Gabriel Cahn,David Samet,Matthew Jeremiah Misner,Andrew Burns,Darshana L. Weerawarne,Mark D. Poliks,Carol Lapinski,Shannon Dugan,Olivier N. Pierron,Antonia Antoniou,Samuel Graham,Azar Alizadeh,Suresh K. Sitaraman +13 more
TL;DR: In this paper, the reliability of a wearable electrocardiogram sensor leadset under tight bending conditions using numerical simulations and experiments is investigated. But the results from the numerical simulations are compared and validated using an analytical model as well as experimental data.
Proceedings ArticleDOI
Heat Dissipation in GaN Power Semiconductor Devices
Adam Christensen,Samuel Graham +1 more
TL;DR: In this paper, a numerical study of the impact of growth substrates on thermal dissipation in GaN devices is presented, which shows that state of the art devices dissipating 10 W/mm of power must be fabricated on high thermal conductivity substrates like GaN or SiC when rear side heat dissipation is utilized.

Probing Growth-Induced Anisotropic Thermal Transport in CVD Diamond Membranes by Multi-frequency and Multi-spot-size Time-Domain Thermoreflectance
Zhe Cheng,Thomas L. Bougher,Tingyu Bai,Steven Y. Wang,Chao Li,Luke Yates,Brian M. Foley,Mark S. Goorsky,Baratunde A. Cola,Samuel Graham +9 more
TL;DR: In this article, the authors used time domain thermoreflectance (TDTR) to measure the thermal properties of an 11.8-m CVD polycrystalline diamond membrane from its nucleation side.
