Wetting of Si surfaces by Au–Si liquid alloys

Abstract: The behavior of liquid Au–Si alloys on Si surfaces covered by a monolayer of gold has been investigated by ultrahigh-vacuum scanning electron microscopy. On the (111) surface, the alloy displays a constant contact angle with the surface from the eutectic temperature up to a temperature of 650 °C and thereafter the contact angle increases linearly with temperature. As observed in previous work, the shape of the liquid droplets changes from circular at lower temperature to hexagonal at higher temperature. In con… Show more

“…Au-Si alloy droplets on flat Si substrates and at temperatures of 400-650°C show a contact angle (defined here as the angle within in the liquid) of about 0 ≈ 43°. 179 Au-Si droplets on top of wires are much more spherical, typically exhibiting contact angles of 90-120°. 36 It is evident that the droplet has to undergo some sort of transition in the initial phase of growth, and it is this change of the droplet shape that causes the observed expansion of Figure 14.…”

“…Крім того, міряючи  Y та поверхневу енергію  lv , можна оцінити енергію адгезії W a . Наприклад, для золота, срібла, міді та кремнію   1400 мДж/м 2 [82],   1140 мДж/м [77],   1720 мДж/м 2 [77] та   2000 мДж/м 2 [83] відповідно. W a характеризує термодинамічну стійкість меж розділу між різ-норідними матеріялами та широко використовується на практиці для прогнозування їх потенційних зв'язувальних властивостей.…”

“…Therefore, techniques for controlling the size and dimensions by employing top-down and bottom-up approaches have been widely discussed [10][11][12][13][14][15][16][17][18][19][20]. Nanotechnological approaches, such as melt quenching, the vapor-liquid-solid (VLS) method using metal dielectrics [10][11][12][13][14][15], metal-ion implantation of semiconductors [4,5,16], and pulsed laser irradiation [17,18] have led to a transition in the size and dimensions of metal NPs and the nanostructure in NCSs. The present authors have also reported a novel top-down and bottom-up approach for fabrication of nanostructures such as Laser Induced Periodic Surface Structure (LIPSS)-dots on the surface of Si substrates using single-beam laser irradiation [19,20].…”
