The Bohring World of Niels Bohr In 1913WBohr proposed that electrons are arranged in concentric circular paths or orbits around the nucleus. Bohr answered in a novel way why electrons which are attracted to protons, never crash into the nucleus. He proposed that electrons in a particular path have a fixed energy. Thus they do not lose energy and crash into the nucleus. 7カje energy /eve/ of g/) e/ecro7 5 太e 7eg/O7 g7Ounの のe 70C7eus Were た5がeルfo pe. These energy levels are like rungs on a ladder, lower levels have less energy and work. The opposite is also true if an electron loses energy it falls to a lower level. Also an electron can only be found rungs of a ladder. The amount of energy gained or lost by every electron is not always the same. Unlike the rungs of a ladder, the energy levels are not evenly spaced. 4 gug/fg77 O7 ene79y 75 妨e 977Ou7た Oげ ener9y ee0eg ro 77oVe 7 e/ecfron廊O77 745 prese7t _ene/rgy 7eve/ 7O je exf jgカer oe or to make a quantum leap- The Quantum Mechanical Model Like the Bohr model, the ggg74777 776c7g77Co/ 777Oe/ leads to gugn67ze9 energy levels for an electron.

RHEED法の原理と得られる7つの情報が、この英文に書かれているみたいなのですが、よく分かりません。 分かる方助けてください！🙇‍♂️

INTRODUCTION Reection high-energy electron diHiraction (RHEED) uses a Rnely collimated electron beam with energy of 10-100 keV. The beam irradiates a sample surface with gazing incidence to obtain forward scattered difraction patterms. RHEED enables us to analyze structures of crystal surfaces at atomic levels and also to in situ monitor growth processes of thin films (mo、1988: Ichimiya and Cohen、2004: Peng et al.. 2011). From the arrangement。intensity and profile of the dilraction spots in RHEED patterns as described below in detail、 one can obtain various kinds of information: (1) the periodicity (unit cells) in atomic arrangements. (2) flat- ness of surfaces. (3) sizes of grains/domains of surface structures and microcrystals grown on the surface. (3) epitaxial relation between the grown flms/islands with respect to the substrate. (5) parameters character- izing structural phase transitions. (6) individual atomic positions in the unit cells. and (7) growth styles of thin films and numbers of atomic layers grown. The most important advantages of the method are that it is quite easy to install the RHEED apparatus in Yarious types of vacuum chambers without interfering with other components of apparatuses and to do real- time monitoring during thin-Rlm growths. Because of these advantages.RHEED is nowwidelyusednotonlyin research Iabs of surfaces and thin fims. but also in device production processes in industry Low-energy electron diiraction (LEED、see article Low-ENNERcy ErecroN DirscmoN)。 in which an electron beam of 10-100 eV in energy is irradiated onto a sample surface with nearly normal incidence to obtain back- scattered difraction patterns. is also widely used to analyze the atomic structures of crystal surfaces. Since one has to make the sample face directly to the LEED
