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

After one yearin America, does Japan look diferent to you now? Do you have any reverse culture shock" Miss you. ge Hi Diane。 Thank you for your email 1miss you too Tm back in my normal hife in Japan. Sometimes. my life in America seems like adream. (be ) 1really in Los Angeles? But quite often, 1 have reverse culture shock. For example, in Japan, there are garbage pickups* almost every day. Im my town. Monday is for paper. Tuesday is for plastic. Wednesday is for botles. and so on. Tcant live with this system. In America, 1 didmt have to dg (上 think Japan is too strict about everything so lget angry every day。 TWA back t cal What do you think2 Your fiiend, ak i Sakura Thar's interesting. 1 returned from Japan to America three years ago. and (think ) about the same thing. 1 think Japan is strict. too. but iVs a good thing. Here in America, many people waste too many things and dont recycle。 because our country is big and we have many kinds of things. Tlike the Japanese systemu so lopened a recycling club at my school Amyway* you don't have to worry. Someday* you will like both Japanese and American cultures. There are good and bad things about Japan, and the same goes for America.You will understand that soon.
