MRS Spring Meeting 2016 in Phoenix: Starting out with a tutorial

Finally, the first ever MRS Spring Meeting in Phoenix, Arizona, is here in 2016. It runs from March 28 to April 1. MRS Spring 2016My colleagues Malte C. Gather, Marc A. Baldo, Chihaya Adachi and I are excited to participate in this event with the Symposium EP1: Organic Excitonic Materials and Devices. We are looking forward to a full week of a packed, interesting, and diverse program.

But before the symposium even starts, we have a tutorial to offer: Tutorial EP1: Organic Excitonic Materials and Devices – OLEDs and Lasers. It will run tomorrow, Monday March 28 from 8:30 am to 12 pm. Location is PCC North, 100 Level, Room 125 B.

We are happy to have Chihaya Adachi (Kyushu University) and Stéphane Kéna-Cohen (Ècole Polytechnique de Montréal) as instructors for the tutorial on board. We will hear in-depth introductions to OLEDs and Lasers, respectively. Come and join us tomorrow to kick-off our Symposium EP1 early with this half-day tutorial session. Here are the details:

Part I: Chihaya Adachi 
The first segment will discuss the key properties of organic molecules important for the use in electroluminescent devices, i.e., organic light-emitting diodes (OLEDs). The fact that about 75% of the excitons are formed in an energetically distinct, nonradiative triplet state urges materials designers to come up with innovative solutions. There will be a detailed discussion of a very recent excitonic scheme: thermally activated delayed fluorescence (TADF), which Professor Adachi and his research team recently pioneered.

Part II: Stéphane Kéna-Cohen 
This segment will begin with a review of basic laser physics in the context of organic lasers, briefly surveying state-of-the-art organic lasers and their applications. Electrically pumped organic lasing remains one of the open challenges in the field of organic electronics and the main difficulties toward achieving this goal will be discussed. The second half will cover a new type of laser, dubbed a polariton laser, which has the potential to drastically lower organic laser thresholds. The physics behind such polaritons will be discussed and some of the fascinating physics that have been observed (ballistic propagation, spontaneous vortices, superfluidity) will be described.

See you tomorrow!
