The New Yorker: “Graphene may be the most remarkable substance ever discovered. But what’s it for?”

Material Question: Graphene may be the most remarkable substance ever discovered. But what’s it for?”

By

New Yorker

…Perhaps the most expansive thinker about the material’s potential is Tomas Palacios, a Spanish scientist who runs the Center for Graphene Devices and 2D Systems, at M.I.T. Rather than using graphene to improve existing applications, as Tour’s lab mostly does, Palacios is trying to build devices for a future world.

At thirty-six, Palacios has an undergraduate’s reedy build and a gentle way of speaking that makes wildly ambitious notions seem plausible. As an electrical engineer, he aspires to “ubiquitous electronics,” increasing “by a factor of one hundred” the number of electronic devices in our lives. From the perspective of his lab, the world would be greatly enhanced if every object, from windows to coffee cups, paper currency, and shoes, were embedded with energy harvesters, sensors, and light-emitting diodes, which allowed them to cheaply collect and transmit information. “Basically, everything around us will be able to convert itself into a display on demand,” he told me, when I visited him recently. Palacios says that graphene could make all this possible; first, though, it must be integrated into those coffee cups and shoes.

IWN 2014 – Wroclaw, Poland “Outstanding Poster Presentation”

iwn

Sameer Joglekar, PhD candidate since 2011 with Prof. Tomas Palacios received the Best Poster Award at the International Workshop on Nitride Semiconductors (IWN) held in Poland the week of Aug. 24.  The work which Joglekar presented, titled “Impact of AI2O3 Passivation on the Surface Properties and Schottky Barrier Height of AlGaN/GaN Transistors” was selected from more than 500 presentations at the IWN, the top conference in the field. Inaugurated in 2000, the International Workshop on Nitride Semiconductors is held biennially alternating with the International Conference on Nitride Semiconductors (ICNS), which covers related subject areas.

Mr. Sameer Joglekar, received his Bachelors degree in Materials Science from the Indian Institute of Technology at Mumbai in India, in August 2011. He joined Prof. Palacios’ Advanced Semiconductor Materials and Devices Group as a Ph.D candidate in November 2011. His work focuses on surface plasma treatments and effects of stress on the piezoelectric properties of AlGaN-GaN material systems.

Abstract: We introduce an ac-transconductance method to profile the gate oxide traps in a HfO2 gated AlGaN/GaN Metal-Oxide-Semiconductor High-Electron-Mobility Transistors (MOS-HEMTs) that can exchange carriers with metal gates, which in turn causes changes in analog and pulsed channel currents. The method extracts energy and spacial distributions of the oxide and interface traps under the gate from the frequency dependence of ac transconductance. We demonstrate the method using MOS-HEMTs with gate oxides that were annealed at different temperatures.

EECScon 2014 and Masterworks 2014 raise awareness of high-level student research

Two consecutive venues provide industry, faculty and student guests with full range and depth of research

Whether it is presented in a formal conference hall at the Kendall Marriott or accompanied with large servings of ice cream along the Charles M. Vest Student Street, research carried out by students in the MIT Department of Electrical Engineering and Computer Science (EECS) has gained a strong professional presence around MIT and beyond. This year, EECS decided to pair its cornerstone venues for showcasing student research — EECScon and Masterworks — in one afternoon (April 22), capturing a large and interested group of guests including fellow students, postdocs, research staff, faculty, and industry visitors.

Masterworks 2014

Masterworks is the Department’s annual presentation and celebration of thesis research leading to the degrees of Master of Science (SM) and Master of Engineering (MEng). This year’s Masterworks will be by poster presentation. EECS faculty members will evaluate the posters and presentations to determine the awardee for the 2014 Morris Joseph Levin Award for Outstanding Masterworks Thesis Presentation. In addition several other prizes will be drawn among the participants.

Development of Graphene-based RF Energy Harvesters on Paper

The use of three-dimensional printing is quickly changing the way products are designed and manufactured. However, in spite of the tremendous flexibility and potential of current 3D printers, most of the 3D objects that can be printed today lack of any kind of electronics and intelligence.

At the same time, the recent development of graphene and other two-dimensional electronic materials offers tremendous new opportunities to fabricate electronic circuits on almost any surface. In this project, we will embed these new materials into 3D-printed systems to add sensing and information processing capabilities. The “smart” 3D systems that will be demonstrated will be an important step towards ubiquitous electronics.

The main tasks of this project are:

1. Identify new technologies to embed two-dimensional electronic materials (e.g. graphene) into 3D printed systems.
2. Fabrication of “smart” 3D systems at the Microsystems Technology Laboratories.
3. Characterization of the fabricated 3D systems.
