Single crystal silicon is the most widely used semiconductor material as a substrate material due to its excellent machinability, mechanical stability, and the potential to combine sensing elements and electronics on the same substrate. Circular wafers made of silicon are used as substrate in most MEMS sensors.

Monocrystalline silicon is the most common and efficient silicon-based material employed in photovoltaic cell production. This element is often referred to as single-crystal silicon. It consists of silicon, where the entire solid’s crystal lattice is continuous, …

2019年1月1日 · Single crystal silicon is unique. It is both the foundation of the global microelectronics-based economy and a model material. Although the word “technology” today is associated with the internet, wireless devices, social media, software coding, and “apps,” all these are enabled by dislocation-free single crystal silicon.

2015年1月1日 · Silicon is a hard, brittle material, and at room temperature under stress silicon single crystal elongates elastically until fracture stress appears without significant plastic deformation. Silicon is a group IV element in the periodic table and is a semiconductor with a bandgap of 1.12 eV, which means that pure silicon at room temperature is ...

2019年1月1日 · The single crystal growth methods, and resulting silicon structure, properties, and defects are extremely well studied and documented in the literature. However, single crystal silicon is still today an active subject of intensive study, and continues to be developed and improved for both optimized crystal performance in devices and reduced cost.

Single-crystal silicon (Si) is an important semiconductor material for optoelectronics and micro electro-mechanical systems (MEMS) owing to its excellent optical and mechanical properties [1], [2]. As a typical brittle material, fabricating high-quality surface on single-crystal Si is challenging due to the surface defects and subsurface damage ...
