This research seminar features both presentations by invited speakers from outside Aalto, as well as researchers from the Department of Electronics and Nanoengineering. The regular time-slot is Wednesday morning 10:15 - 11:45, but there are exceptions, depending e.g. on the availability of external speakers. The seminar will be in TU3 at the 1st floor of TUAS building (Maarintie 8, Otaniemi, Espoo), if not otherwise stated in the program.
There is no formal enrollment needed, anyone can attend the seminar anytime. For students who wish to get credits from their seminar attendance, please, simply mark your name on the attendance sheet that is circulated in each session. After 13 attended seminar sessions you are entitled to 1 credit point, and you may repeat this and earn another credit point as many times as you like. Contact ZacharyTaylor (zachary.taylor@aalto.fi) or Sergei Tretyakov (sergei.tretyakov@aalto.fi) to sign in! You can also enroll yourself (link)

Wed 15.01 Sergei Tretyakov: Physical meaning of the dipole radiation resistance in lossless and lossy media. Abstract: If the medium is lossless, the radiated power propagates to infinity, and the apparent dissipation is measured by the radiation resistance of the dipole. If the medium is lossy, the power exponentially decays. Shall we conclude that the radiation resistance is zero because the fields at infinity tend to zero? If the medium is lossy, all the emitted power is dissipated in the medium and can be evaluated via volume integration. But what if the loss parameter tends to zero? What is the limiting value of the volume integral of the absorption power density? Let's try to answer these questions and discuss theoretical and practical implications of the results.
Thursday 16.01, at 15:45, in Micronova small lecture
hall 2191, Tietotie 3. Prof. Alberto G. Curto from
TU/e - Eindhoven University of Technology (The Netherlands): Excitons in nanophotonic
landscapes: fluctuating, diffusing, annihilating. Abstract: Excitons in two-dimensional
semiconductors exhibit rich dynamics. Their fluorescence is sensitive to the
nanoscopic environment. Excitons also diffuse and interact with each other,
notably to reduce light emission at high densities through exciton-exciton
annihilation. In this seminar, first, we will demonstrate that an atomically thin semiconductor
can display substantial fluctuations in fluorescence intensity influenced by
its environment, in analogy with blinking in quantum dots. Second, we will
discuss strategies to increase the number of photons emitted by a 2D
semiconductor. We focus on how exciton diffusion and annihilation impact
fluorescence enhancement based on nanophotonic structures. Controlling exciton
dynamics in the form of fluctuations, diffusion, or annihilation has direct
implications for stable single-photon sources, sensors based on excitons, or
high-power light-emitting devices.
