“…As the distance between the source and substrate increased at low pressures, the growth rate was reported to decrease due to the divergence of the gas. Research works by Nagayoshi and Suzuki observed that the deposition rate increased as the source temperature increased for a deposition under vacuum, in agreement with a sublimation limited case [22]. They also varied the substrate temperature showing for a source temperature of 650°C and a substrate temperature of 520°C, the growth rate reached maximum in that case.…”

Semiconductors are the key materials in many of our modern day devices, such as sensors, integrated circuits, energy harvesting devices, optoelectronics and so on. However, apart from two known elemental semiconductors that are silicon and germanium, we have been using many of the synthesized ones since the microelectronic revolution known as invention of transistor. Numerous compound semiconductors since then have been synthesized, grown, deposited or simply fabricated by numerous processes in the scientific community. To avoid associated chemical disposals or keep safe from toxic or combustible gas usages in any semiconductor fabrication facilities, many researchers choose physical vapor deposition as the simplest method. One of such processes is called Close-Spaced Sublimation (CSS), which is a kind of thermal evaporation by nature. This chapter would give a comprehensive outline on CSS as one of the most advantageous semiconductor deposition processes for many compound semiconductors having relatively low evaporation temperature. Cadmium telluride (CdTe) is one of the examples utilized for solar cell absorber materials since the early 1980s using CSS technique. Therefore, growth of CdTe thin films by CSS and its utilization in thin film solar cells will be discussed to comprehend the ultimate benefits of the close-spaced sublimation (CSS) process.

Te aggregation at the initial growth stage of CdZnTe films deposited by close-spaced sublimation (CSS) is studied with the combination of energy dispersive spectroscopy (EDS) and high resolution transmission electron microscopy (TEM). Te atoms aggregate in the form of Terich amorphous layers, and then these layers grow into stoichiometric and crystalline compounds through interdiffusion as the films thickened. Te aggregation is led by the high dissociation energy of Te-Te bond and the less volatile nature of Te 2 molecules than Cd and Zn molecules absorbed on the substrate.
