Atomic structure of nanosystems from first-principles simulations and microscopy experiments

Workshop

Topics

Introduction

Recent progress in the transmission electron microscopy (TEM) as well as in scanning tunneling and atomic force microscopy (STM/AFM) made it possible to not only unravel the atomic structure of various systems with a resolution of better than 0.1 nm, but also carry out elemental analysis and determine the types of particular atoms in the sample. Moreover, based on spectroscopic in-situ techniques (for example, electron energy loss spectroscopy, EELS), the charge state and the bonding configuration of individual atoms and point defects in the material can be identified.

The unequivocal interpretation of the experimental results can considerably benefit from the juxtaposition of the images to the results of first-principles calculations. With regard to TEM, the accuracy of the measurement is now so high that in addition to the information on the atomic configuration (that is atom positions), the detailed information on the spatial distribution of the electron density and on the electron structure of the system is required. Likewise, the microscopy knowledge on the local electronic structure of the system is extremely important for the correct interpretation of the experimental STM and AFM images and spectra.

First principles simulations, and specifically density-functional theory (DFT) approaches, have provided lots of insight into the electronic structure and properties of various solids. They also considerably extended our understanding of how the STM/AFM or TEM images are formed. Besides, using DFT and time-dependent DFT molecular dynamics, one can simulate the manipulation of the nanostructures by SPM tools and the changes made to the system, e.g., production of defects under electron irradiation and their time evolution.

In this workshop we are going to bring together the TEM/STM/AFM experts and computational materials scientists to discuss the progress in TEM/ STM/AFM analysis and visualization of the atomic structure of nanosystems. The workshop will be focused on various nanostructures, and will include a wide variety of substrates from graphene to complex oxides.

Physics Boat 2013 is the third time we take science on a cruise. The previous event was held in 2012. The workshop consists of invited and contributed talks as well as posters. Invited and contributed speakers will cover the recent progress in simulations and the relevant experimental areas.

We also organize the Towards Reality in Nanoscale Materials workshop in Lapland in the winter.

Important dates

Venue

Boat

The workshop will take place on a board of a ferry going from Helsinki to Stockholm via Aland and back.

The workshop will start at 11:00 am with lunch on 4th of June, and we will work till 8 pm (with ca 1 hour break to see the departure, Helsinki archipelago and the Suomenlinna fortress). Next morning (the ferry arrives in Stockholm at 9:30 am) will be used for discussions, which can take place in Stockholm downtown.

The presentations will continue again at about 2 pm, and they will last until 8-9 pm. After returning to Helsinki on the 6th, we remain on board of the ferry till 3 pm, and the presentations will continue from 9 am on till 3 pm with a lunch break.

If you cannot arrive in Helsinki early enough on 4th of June, we recommend that the you come on the 3rd and spend the night in Helsinki.

Travel

Bus from the airport

There is a direct bus from the airport to downtown Helsinki (bus number 615/615T). The trip will take about 30 minutes (615) to 45 minutes (615T) and will cost 4 euro (can be bought from the driver). You can also take Finnair Express bus to downtown which is quicker, but will cost 6 euro. From downtown, you need to come to the ship terminal (Olympiaterminaali), which can be reached with tram 3T (included in the 4 euro bus ticket if tram is entered within 90 minutes from buying the ticket). The tram trip will take about 10 minutes. Walking the same distance will take about 15 minutes.

The easiest way to plan the trip from and to the airport is to use the journey planner (available in English). Journey planner will also provide you with maps of the journey.

Taxi

Another option is to take taxi from the airport. The price will be about 40 euros, and the trip will take ~30 minutes depending on the traffic.
