(1) IT WAS CONFIRMED THAT THE CLEANLINESS OF CRYSTAL SURFACE CAN BE QUANTITATIVELY STUDIED BY LOW-ENERGY ELECTRON TRANSMISSION SPECTROSCOPY (LEET) WHICH IS THE SIMPLEST ELECTRON SPECTROSCOPIC TECHNIQUE.(2) THE GROWTH OF WELL ORDERED MONO-MOLECULAR LAYER ON MoS_2 CRYSTAL SURFACE COULD BE DETECTED SENSITIVELY WITH LEET FOR PHTHALOCYANINE'S,BTQBT [bis (1,2,5-thiadiazolo) -p-quinobis (1,3-dithiole)] AND C_<60> WITHOUT INTRODUCING RADIATION DAMAGES INTO THE FILMS.(3) THE MOLECULAR ORIENTATION AND TWO-DIMENSIONAL STRUCTURE OF THIN FILMS OF PHTHALOCYANINE'S AND BEQBT ON MoS_2 SURFACES WERE DETERMINED WITH ANGLE-RESOLVED PHOTOELECTRON SPECTROSCOPY,HIGH-RESOLUTION ELECTRON ENERGY LOSS SPECTROSCOPY,LOW-ENERGY ELECTRON DIFFRACTION AND PENNING IONIZATION ELECTRON SPECTROSCOOPY.THE RESULTS OBTAINED BY THESE METHODS WERE CONSISTENT WITH THOSE BY LEET.(4) FOR AICI-PHTHALOCYANINE,WE FOUND THAT THE CI ATOM PROTRUDING OUTSIDE THE FILM SURFACE IN THE MOST STABLE STATE OF THE MONO-MOLECULAR LAYER.

(1)证实了低能电子透射光谱（LEET）是最简单的电子光谱技术，可以定量研究晶体表面清洁度。(2)用LEET技术可以灵敏地检测MoS_2晶体表面上有序单分子层的生长，并对酞菁、BTQBT [bis（1，2，5-thiadiazolo）-p-quinobis（1，3-dithiole）]和<60>C_2进行检测。(3)用角分辨光电子能谱、高分辨电子能量损失谱、低能电子能谱和潘宁电离电子能谱研究了MoS_2表面酞菁和BEQBT薄膜的分子取向和二维结构，所得结果与LEET结果一致。(4)对于AlCl-Phthalocyanine，我们发现Cl原子在单分子层的最稳定状态下突出于膜表面之外。
