The improvement of advanced materials that are used in Aerospace Industry is and will remain critical. Protective coatings and enhanced technologies are essential in order to further develop the properties of materials. During the production stages, chemical vapour deposition processes are being widely employed. The prerequisite to obtain high performance advanced substrate materials with high performance, conformity, uniformity and compact coatings makes chemical vapour deposition an ideal method for demanding processes.

Chemical Vapour Deposition (CVD) is a multipurpose and widely used process fitting for the production of coatings, powders, fibers and monolithic components. Essentially, it is a method where one or more volatile precursors are transferred via the vapour phase to the reaction chamber, where the decomposition starts on a heated substrate. It belongs to the additive manufacturing lineage, since CVD adds layers onto a substrate surface. Main advantages of CVD are:

  • Films produced are quite conformal
  • Plethora of films can be deposited with very high purity
  • High deposition rates and high degree of control of composition, internal stresses and defect density
  • Excellent step coverage


Chemical Vapour Deposition (CVD) is a thin film deposition method that occurs at the surface which is destined for coating. Ultimately, reaction parameters can be controlled offering flexibility to the end user regarding coating composition, crystallinity, thickness of thin film and internal stresses. One of the greatest advantages of this method is the homogeneity of coating thickness for a wide size range of substrates and 3-dimensional parts. The usage of CVD is beneficial by a wide range of Industries and Delta Nano – Engineering Solutions Ltd., can contribute for enhancing the future of chemical reactors and advanced materials.



Marine industry is highly diversified, competitive, and pioneering in its own right. Delta Nano-Engineering Ltd. is here in order to provide R&D solutions to a variety of issues that concern this industry. Existing equipment or processes can be enhanced and improved, where CVD is applicable, or in providing water purification solutions.



Medical devices have become more sophisticated especially during the last two decades. The use of appropriate coatings has become essential for advanced functioning, and more importantly, for biocompatibility. Biocompatible devices are designed in order to circumvent life– threatening situations towards the end receiver; the patient. Medical coatings are important in order to enhance the performance of the device, and also guard the patient. The challenges for such applications are:

  • Biocompatibility
  • Coating adhesion
  • Uniformity through complex 3D shapes
  • Strength
  • Resilience

Chemical Vapour Deposition is the ultimate choice, since it additionally creates thick, high purity, or thin films through conventional control of the composition procedure.



Semiconductor materials can be found in optoelectronic devices such as light–emitting diodes (LED’s) and infrared detectors.

A light–emitting diode is a semiconductor device that emits visible light when an electric current passes through the device. The light is monochromatic, occurring at a single wavelength, ranging from red (approximate wavelength at 700 nanometers) to violet-blue (nearly 400 nanometers of wavelength), whilst some LED’s produce infrared (IR) energy (830 nanometers of wavelength or longer), known as infrared – emitting diode (IRED). Additionally, LED’s can be manufactured to produce light in the ultraviolet range (approximately 365 to 395 nanometers). The advantages of LED’s and IRED’s include:


  • Low power operational mode: Most types may be operated with simple batteries
  • High efficiency: Great percentage of the power supplied to a LED or IRED is converted in the required form with negligible heat production
  • Long operational life: If it is installed accurately and under normal conditions, a LED or IRED can operate for decades.

Typical applications of the LED and IRED diodes can be found in Water Purification Systems by eliminating harmful microorganisms, whilst being favourably compared with other water disinfection systems in terms of cost, labour, and the necessity for technically skilled personnel.



Semiconducting materials form the basis of countless devices that are broadly used daily, such as complementary metal – oxide semiconductor (CMOS) integrated circuits (ICs), photonic and optoelectronic devices and finally micro – electro – mechanical systems (MEMS). Chemical Vapour Deposition (CVD) is one of the most efficient method for producing and developing semiconducting thin films and multifaceted micro and nano – structures. The CVD technique is multipurpose and can be adjusted in such way in order to generate homoepitaxial and heteroepitaxial materials along with polycrystalline and amorphous materials. Many divisions of semiconducting materials can be formed such as multi-layer stacks, nanowires, nanorods, or even quantum dots. Delta Nano – Engineering Solutions Ltd., can contribute in designing and manufacturing of custom CVD reactors according to the prerequisites of our Clients.


The necessity for improving materials is seeing accelerating interest in renewable energy research and development. Chemical Vapour Deposition is an adaptable method for formatting such steps including diffusion, deposition of anti-reflective coatings, oxidation and silicon epitaxial deposition. CVD processes are widely used in solar cell manufacturing, as research has been aimed at increasing the efficiency rate of photovoltaic cells and solar arrays. Depositions varying from crystalline silicon in a c – Si solar cell to the deposition of a range of different materials in thin film solar cells (TFSC’s). Delta Nano – Engineering Solutions Ltd., can engineer, design and manufacture custom CVD reactors following the necessities of their Clients.

tcoTransparent conductive oxide (TCO) coatings are fundamental in large scale thin film solar cell manufacturing. Delta Nano – Engineering Solutions Ltd., can design, engineer, and manufacture custom atmospheric pressure chemical vapour deposition reactors (APCVD) for fluorine doped tin oxide coatings (SnO2:F or FTO) appropriately for the needs of our Clients. TCO’s can be coated onto soda lime glass sheets and on a broad range of metal foils and plastics whilst, they can be enhanced for rough coating with great haze for solar applications and additionally with soft haze for the production of Low – E and several smart glass applications.
