HEED

...In 1928, it was performed by Toshiaki Nakamura and is known as a direct verification of matter waves. Since 1960, with the development of ultra-high vacuum technology, research on solid surfaces using low-energy electron diffraction (abbreviated as LEED, with an acceleration voltage of several tens to several hundred volts) and reflection high-energy electron diffraction (abbreviated as RHEED, with an acceleration voltage of several kV to several hundred kV) has become popular. Figures a and b are conceptual diagrams of high-energy electron diffraction (abbreviated as HEED) and LEED diffraction devices, respectively. ...

…1928)らにより行われ，物質波の直接的検証として知られている。1960年以降，超高真空技術の発達に伴い，低速電子線回折(LEED（リード）と略称し，加速電圧数十～数百V)，反射高速電子線回折(RHEED（アールヒード）と略称し，加速電圧数kV～数百kV)による固体表面の研究が盛んになった。図のa,bはそれぞれ高速電子線回折(略称HEED（ヒード）)およびLEEDの回折装置の概念図である。…
