Recently, it is found that structures formed upon alkali-metal adsorption are strongly dependent on substrate temperature. At low temperature, alkali-metal atoms form overlayers occupying the highest coordination sites of substrate surfaces. At room temperature, some adsorption systems do no exhibit overlayer-formation. Instead, alkali-metal atoms replace substrate surface atoms initially following ordered surface-alloy formation with increasing coverage.
