Ever wonder how efficient LED lighting is, compared to traditional florescent lighting? In this blog post, we demonstrate how to analyze LED efficiency with multiphysics modeling.

Integrated Circuit Design and the Photolithography Process

October 4, 2013

When designing products on the nanometer scale, physics interactions that are considered negligible on the larger scale make their presence known. One such case where these forces must be taken into account is in the design of integrated circuits, where understanding and optimizing the effects of van der Waals forces, attractive forces, and surface tension become vitally important to creating a robust design. As technological advancements call for both the size of integrated circuits to decrease and the density of […]

The Graphene Revolution: Part 5

May 8, 2013

In a paper titled “Choosing a Gate Dielectric for Graphene Based Transistors“, the applications of a semiconducting form of graphene are examined. As we have seen before, single-layer graphene is not a semiconductor, it is a zero bandgap conductor (a semimetal). Efforts are well underway to introduce bandgaps to graphene, which would make it semiconducting with a room temperature mobility an order of magnitude higher than silicon. The race is already underway to find applications for such a material once […]
