IT-5-O-2999 Direct observations of local electronic states in a quasicrystal by STEM-EELS
Email of the presenting author: [email protected] Quasicrystals (QCs) have long-range ordered complex structure without periodicities. Stability of QCs has been discussed in terms of energetic gains in electron systems, because most QCs reveal pseudogaps in their density of states around Fermi level. In fact, many QCs have been discovered by tuning valence electron density based on Hum...
متن کاملCompressive STEM-EELS
The collection of electron energy loss spectra (EELS) via scanning transmission electron microscopy (STEM) generally requires a specimen to withstand a large radiation dose. Moreover, significant drift can occur while the spectra are collected. Recent advances in electron microscopy have shown that a data reduction of up to 90% is possible for HAADF/ABF imaging and TEM video [1, 2, 3]. These ad...
متن کاملFast STEM Spectrum Imaging Using Simultaneous EELS and EDS
Introduction Up to now, researchers performing analytical investigations in the transmission electron microscope typically had to choose between analytical spectroscopy techniques. They might choose energy dispersive X-ray spectroscopy (EDS) analysis when working with thick samples containing high-Z elements or choose electron energy-loss spectroscopy (EELS) when studying low-Z materials in thi...
متن کاملon the equivalence of constructed-response and multiple-choice : stem-equivalent, stem non-equivalent but content equivalent, and stem and content non-equivalent items in reading comprehension using multifaceted rasch
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
STEM/EELS Analysis of Conversion Reactions in Cycled FeOF/C
Transition metal fluoride/carbon nanocomposites have been under extensive investigation in the past ten years due to their theoretical high capacity in the range of 500 to 800 mAh/g [1]. In this study, the structural changes of FeOF/C positive electrode during lithiation/delithiation have been studied as a function of number of cycles (up to 20) under constant cycling current of 50 mA/g and at ...
