CdS Thin Film Transistor Threshold Voltage Shift Investigation

W. Wondmagegn [1],
[1] Frostburg State University, Frostburg, MD, USA

A threshold voltage shift of CdS Thin Film Transistor is studied using the COMSOL Multiphysics® software's Semiconductor Module. Drift-diffusion (DD) simulation model is used in which the basic equations used are similar to those used for a single-crystal device except that traps and ... Read More

A Prediction of Energy Piles’ Long-Term Operation Using a Coupled Thermo-Hydro-Geomechanical Model

T. Vu [1], L. Medina [1], D. de la Cruz [1], J. Ramirez [1], B. Xu [1]
[1] University of Texas - Rio Grande Valley, Edinburg, TX, USA

An energy pile harvests geothermal energy to heat and cool a building by integrating ground heat exchanger (GHX) pipes into the building’s deep foundation, and extracts heat from the ground in the winter to heat buildings and injects heat into the ground during the summer. In areas with ... Read More

Simulating Organogenesis in COMSOL Multiphysics®: Comparison of Methods for Simulating Branching Morphogenesis

L. D. Wittwer [1], M. Peters [1], S. Aland [2], D. Iber [1],
[1] ETH Zürich, Zurich, Switzerland
[2] University of Applied Sciences, Dresden, Germany

Organogenesis, the genesis of organs during embryonic development, is an active research field involving biologists, mathematicians and computational researchers. Fundamental questions of the formation of shape and the control of growth are still not answered. We focus on the development ... Read More

Neuromodulation is the use of electromagnetic fields to modulate the human nervous system, typically to treat neurological disorders. Electroceuticals is an ambitious program to modulate any nerve, anywhere, anytime, for any reason — to treat disease, disorders, and enhance or interface ... Read More

Modeling of Electro-Thermal Microbolometer for Thermal Imaging

A. Nowicki [1], A. Bennecer [1],
[1] Mechanical Engineering, University of Northampton & Gdańsk University of Technology, Gdańsk, Poland
[2] Engineering, University of Northampton, Northampton, United Kingdom

A Microbolometer is a specific type of uncooled infrared radiation detector used in thermal cameras, which converts the incoming energy into a proportionate electrical signal, which is then amplified, processed and displayed, typically on the thermal camera’s LCD viewer. The main ... Read More

V. Barati [1], H. Reith [1], G. Li [1], D. A. Lara Ramos [1], G. Schierning [1], K. Nielsch [1],
[1] Leibniz Institute for Solid State and Material Research, Dresden, Germany

Thermoelectric generators (TEGs) which convert heat into electrical energy due to Seebeck effect, have recently attracted a great attention as green and sustainable energy sources. One of the challenges in the field of thermoelectric devices is the design optimization in order to make ... Read More

COMSOL Multiphysics® Simulation of Functionalized 3D Biocompatible Porous Graphene Composites

E. Lacatus [1],
[1] Polytechnic University of Bucharest (UPB), Bucharest, Romania

Graphene is an allotrope of carbon having the structure of a plane sp2-hybridized atom with a band length of 1.42Å, and representing the basis of any carbonaceous material. This 2D material consisting on pure forms of carbon exhibits high crystalline and electronic quality. Thus, despite ... Read More
