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 […]

Graphene can be created by way of thermal decomposition at high vacuum. In order to design and optimize these high vacuum systems engineers might look to simulation, but there are currently not many modeling tools that are up to the task. Let’s have a look at how vacuum systems are relevant to graphene production, why you should simulate them, and how.

The Institute of Electrical and Electronics Engineers (IEEE) is doing some really cool things for its members. Chances are that you have attended their top rated conferences, downloaded papers from IEEE Xplore, or participated in one of many local chapter events. For electrical engineers like me, IEEE certainly is a rock to lean on for continued education and to connect with colleagues from around the world. Even if you are not a member you can tap into IEEE resources such […]

Each year in May we host a multiphysics simulation workshop specifically for U.S. government employees. This year’s agenda will provide attendees with an overview of COMSOL Multiphysics, tutorials, a user presentation, and more — all in a setting that allows classified work to be shared among federal employees and contractors only.

Smart materials are able to convert one form of energy to another. These materials can be either solid or fluid, and are typically located within what’s called a smart structure. What makes these materials and structures so “smart”? Let’s find out.

In a previous blog entry I discussed some of the exotic properties of graphene. The fact that graphene consists of a single layer of atoms means the aspect ratio of any graphene-based structure may be very high. High aspect geometries present their own array of modeling challenges.

About 13% of the world’s power is nuclear. During the 1990′s, this figure was almost 18%. This trend may continue to decline or undergo a renaissance, but in the meantime nuclear waste disposal remains a hot topic among engineers and governmental agencies. Safe procedures for the disposal of nuclear waste have been in place for decades, and continued improvement of these techniques remain in discussion today.

What does it take to get started using COMSOL Multiphysics? Of course, it depends on where you set the bar. However, grasping the workflow and handling the basic tools can be relatively easy to pick up. To make this process even smoother, first-time users will benefit from the recent major update of the COMSOL Multiphysics instruction manual. The book, Introduction to COMSOL Multiphysics, is a valuable tool for learning COMSOL simulation software and the new version is now available for […]
