The scanning tunneling microscope ( stm ) is our prime instrument to study the above mentioned topics 我們的主要研究?jī)x器為掃描穿隧顯微鏡( stm ) 。
Scanning tunneling microscope ( stm ) , introduced in the early 1980s ' , is a new type of microscope and a new technique for surface analysis 納米技術(shù)領(lǐng)域中的一重要成員? ?掃描隧道顯微鏡( scanningtunnelingmicroscope ,縮寫(xiě)為stm )有著廣泛的應(yīng)用前景,掃描隧道顯微鏡是八十年代初發(fā)展起來(lái)的一種新型表面分析儀器。
In this article , we discussed advantages of scanning near - field optical microscope ( snom ) over conventional optical microscope , atomic force microscope ( afm ) , and scanning tunneling microscope ( stm ) 摘要本文首先介紹近場(chǎng)光學(xué)顯微鏡的基本原理,然后介紹近場(chǎng)光學(xué)顯微鏡與傳統(tǒng)光學(xué)顯微鏡、原子力顯微鏡、掃描隧道顯微鏡相比,在生物膜研究方面的優(yōu)勢(shì)。
Invented by dr . gerd binnig and heinrich rohrer , the scanning tunneling microscope ( stm ) is the first device that gains the real space image of atoms . ever since then , great varieties of scanning probe microscopes ( spm ) were developed on the base of stm 掃描隧道顯微鏡( scanningtunnelingmicroscope ,簡(jiǎn)稱stm )最早于1982年由葛?賓尼( gerdbinnig )博士和海?羅雷爾( heinrichrohrer )博士率先研制成功,并在世界上首次觀察到原子的實(shí)空間圖像。
We introduce the fabrication of all samples and anneal of fexcu ( 1 - x ) granular film in detail . the configuration of granule film is investigated by scanning tunneling microscope ( stm ) . the matter phase is analyzed by x - ray diffraction ( xrd ) . the hysteresis loop of co / al2o3 / feni magnetic tunnel junction is studied by vibrating sample magnetometer ( vsm ) . we use microresistance test system ( mts ) to investigate the character of resistance , conductance , voltage and current 用掃描電子顯微鏡( stm )觀察顆粒膜樣品的表面形貌;用x ?射線衍射儀( xrd )對(duì)顆粒膜樣品進(jìn)行物相分析;用振動(dòng)樣品磁強(qiáng)計(jì)( vsm )對(duì)co al _ 2o _ 3 feni隧道結(jié)的磁滯回線作了研究;用微電阻測(cè)試系統(tǒng)對(duì)樣品電阻、電導(dǎo)、電流、電壓相關(guān)特性進(jìn)行詳細(xì)的研究。
