Image contrasts in the scanning electron microscopy
Konvalina, Ivo ; Hovorka, Miloš ; Mikmeková, Šárka ; Müllerová, Ilona
When interpreting the image contrasts we have to consider all instrument parameters that influence the transport of signal electrons to the detector. Several examples are presented.
Mapping of dopants in silicon by injection of electrons
Hovorka, Miloš ; Konvalina, Ivo ; Frank, Luděk
We have focused on planar p-type structures of various dopant densities, embedded In an n-type substrate. The samples were observed in UHV electron microscope with the cathode lens. Imaging by means of secondary electrons and its quantifiability was verified and the method was extended to very low energies.
Prospects of the scanning low energy electron microscopy in materials science
Frank, Luděk ; Mikmeková, Šárka ; Konvalina, Ivo ; Müllerová, Ilona ; Hovorka, Miloš
Employment of the scanning low energy electron microscopy (SLEEM) has been slowly making its way into the field of materials science, hampered not by limitations in the technique but rather by the relative scarcity of these instruments in research institutes and laboratories.
Vacuum level by very low energy electron reflectivity vacuum level by very low energy electron reflectivity
Pokorná, Zuzana ; Frank, Luděk
The local density of states is an important characteristic of solids, in particular the crystalline ones. A scanning electron microscope equipped by the cathode lens can effectively map the reflectivity of very low energy electrons with a high lateral resolution.
Analysis of a combined electrostatic and magnetic objective lens
Konvalina, Ivo ; Müllerová, Ilona
Cathode lens (CL) is an electron optical element commonly used in the photoemission electron microscopy (PEEM), low energy electron microscopy (LEEM) and last but not least in the scanning electron microscope (SEM). ens. The sequential arrangement of electrostatic and magnetic fields was considered.
Study of intrinsic stress in CNx films prepared by magnetron sputtering device using electron microscopy
Mikmeková, Eliška ; Sobota, Jaroslav ; Caha, O. ; Mikmeková, Šárka
Preparation and analysis of amorphous carbon nitride thin films (CNx) deposited by RF magnetron sputtering device on silicon wafers (100) is reported.
Study of intestinal mucosa in high pressure conditions of variable pressure SEM
Flodrová, Eva ; Neděla, Vilém
Nature state of low conductive wet biological samples cannot be studied in high vacuum environment of conventional scanning electron microscope. This work deals with study of the chemically fixed but fully hydrated intestine villi in high pressure conditions of variable pressure SEM.
Sborník příspěvků multioborové konference LASER50
Růžička, Bohdan
Konference LASER50 byla setkáním profesionálů z nejrůznějších oborů se společným jmenovatelem, kterým je laser. Toto setkání si kladlo za cíl vytvořit podmínky pro úspěšné navázání osobních i odborných vztahů.
Proceedings of the 12th International Seminar on Recent Trends in Charged Particle Optics and Surface Physics Instrumentation
Mika, Filip
Proceedings of seminar on Recent Trends in Charged Particle Optics and Surface Physics Instrumentation. The seminar was held in Skalsky Dvur. The seminar is periodically prepared by ISI AS CR v.v.i., Department of Electron Optics and it is a traditional opportunity for scientific discussion of topics regarding creation and formation of charged particles beams and its usage.
