Graphene the Material Question

morreale Tuesday 13 of January, 2015
The New Yorker website has posted a detailed history of graphene, its applications, and the difficulties of fabricating devices with the material. The story chronicles the discovery of graphene by Andre Geim and Konstantin Novoselov along with the research activities that have occurred since its discovery in 2004.


Graphene on the BBC One Show

morreale Monday 12 of January, 2015
The BBC One Show has produced this short interesting video on the merits of graphene. The flexibility of graphene is nicely demonstrated as are some presumably graphene flex touch pads. I really like the presenters enthusiasm for graphene and hope that the difficulties in manufacturing graphene devices are solve relatively soon.

Introduction to semiconductor devices

morreale Monday 15 of December, 2014
The nanoHUB has a nice Introduction to Semiconductor Devices web page/tool that that covers the following topics:
  • Crystal structures and lattices
  • Band models and structure
  • Bulk semiconductors
  • PN junctions
  • Bipolar Junction transistors
  • MOS capacitors
This introduction as part of the Assembly of Basic Applications for Coordinated Understanding of Semiconductors (ABACUS) tool used to integrate lectures, simulators, and labs into a common platform.

Exascale Computing--fact or fiction?

morreale Wednesday 10 of December, 2014
The IEEE Solid State Circuits Society has posted and archive of the talk Exascale Computing--fact or fiction? by Intel fellow Shekhar Borkar. It was a very good talk and covered the technical challenges that are on the road to exascale computing. This includes compute function, memory, interconnect, resiliency, and software. A teraflop system requires ~1kW of power today, and a exascale system would consume 20 MW so power scaling is a major challenge, for example.

CNF user recipe wiki

morreale Wednesday 10 of December, 2014
The Cornell Nanoscale Science and Technology Facility (CNF) has a new wiki where users can post their process recipes for the various tools at the facility. The recipes are a great starting point for a fabrication process. The wiki also contains manuals and tutorials on the facilities tools.


Emerald Cloud Lab

morreale Thursday 04 of December, 2014
Emerald Cloud Lab allows life sciences researchers to run automated experiments in a lab in the cloud. In this system, you can design an experiment, conduct the experiment, exam the data, and analyze the results. Emerald Cloud lab offers about a 40 experiments now and many more coming soon. The system is build around Mathematica so there is a rich set of data analysis functions available. This short video shows the automated operation of the lab in the cloud.
