About CenErgy

 

The performance of advanced functional materials is most often dictated by the composition, state as well as micro- and nanostructure of the material, and thus in-depth knowledge of these parameters is needed to design and optimize materials. Advanced electron microscopy can provide high-resolution information to describe the majority of these features. The overall aim of this summer school is therefore to equip students with the fundamental knowledge to perform advanced electron microscopy investigations and data analysis in practice to extract relevant information from advanced materials.

 

CenErgy is aimed at PhD students who are already familiar with the fundamentals of scanning and transmission electron microscopy and who are relatively experienced microscope users. A typical CenErgy participant already has spent 10 of hours independently operating an electron microscope and analyzing data and is now looking to dig deeper into techniques they are familiar with or learn a new electron microscopy technique relevant to the their coming research needs. CenErgy students typically already have materials science questions that need investigation by a specific, or range of electron microscopy techniques that helps relate internal structure to the properties of their material system.

 

Thus, CenErgy starts therefore directly with lectures focusing on exploiting advanced electron microscopy techniques and practical exercises based around advanced techniques before quickly progressing to hands-on microscopy. Each experimental session has been designed to investigate selected specimens relevant for each of the selected topics. We are unable to investigate samples provided by participants due to time restrictions and specific sample preparation needs. However, that being said you participants are very welcome to bring specimens that we can provide advice on during the many opportunities for discussion with our educators and fellow participants.

 

CenErgy aims to provide a learning environment that maximizes active learning and time spent on microscope operation and data analysis compared to attending lectures. CenErgy participants research a wide range of materials systems thus the summer school promotes interdisciplinary discussions and the creation of new student networks across research fields.

 

Participants who meet CenErgy's learning objectives will be able to:

  • Describe the various components of scanning and transmission electron microscopes and their operating principles focusing on 3D-SEM, HP-SEM, ETEM, and spectrum imaging
  • Explain physical principles behind EDX and EELS
  • List the requirements for environmental TEM
  • Interpret image contrast in SEM and TEM
  • Identify important experiment parameters for elemental quantification
  • Identify limitations on sample and resolution of ETEM compared to conventional TEM
  • Explain principles behind monochromation and aberration correction in EM
  • Identify and list limitation of micro- and nanoscale characterization by means of 3D-SEM, HP-SEM, ETEM, and spectrum imaging respectively
  • Plan and perform an experiment using 3D-SEM, HP-SEM, ETEM, or spectrum imaging in order to reveal information on the micro- or nanoscale on samples of interest
  • Interpret results of experimental work based on the advanced electron microscopy methods in question
  • Communicate the outcome of the experimental work in relation to the underlying theory
