Ultra Thin Film

The paper will present an overview of our latest results using various ultra-thin film amorphous carbon deposition techniques, and focus on first to grow studies, nano-characterisation of the electrical, mechanical and barrier properties associated with films grown on various substrate types applied to the magnetic recording industry. Although some of the characterisation is carried out on 10nm coatings, the nanomechanical measurements are performed on samples with thickness values between 30nm to 200nm. This overview of our work deals with PECVD deposition techniques and examines ultra-thin film growth on Si and Al 2 O 3: TiC substrates. Some results are presented on the functional benefits of doping a-C:H films with Silicon and Nitrogen. All the work is related to the ability to produce effective 3nm to 10nm overcoat layers for new magnetic recording applications.

Cluster Diffusion

In this paper, we briefly review a model that describes the diffusion-controlled aggregation exhibited by particles as they are deposited on a surface. This model allows us to understand many experiments of thin film deposition. In the Sec. 1, we describe the model, which incorporates deposition, particle and cluster diffusion, and aggregation. In Sec. 2, we study the dynamical evolution of the model. Finally, we analyze the effects of small cluster mobility and show that the introduction of cluster diffusion dramatically affects the dynamics of film growth. Some of these effects can be tested experimentally.

Hydrogenated Amorphous

Diamond-like carbon refers to forms of amorphous carbon and hydrogenated amorphous carbon containing a sizeable fraction of sp 3 bonding, which makes them mechanically hard, infrared transparent and chemically inert. This paper discusses the various thin film deposition processes used to form diamond-like carbon and the deposition mechanisms responsible for promoting the metastable sp 3 bonding.

Deposition Techniques

Thin film is used for sensing and electronic devices applications. Various techniques are used for thin film deposition. This chapter presents the Spray pyrolysis deposition technique used for the growth of thin films sensing and device material. Spray pyrolysis is an inexpensive method to grow good crystalline thin film compared to other thin film deposition techniques. The chapter gives an overview of the spray process used for thin film deposition. Basic setup for this process is explained. Parameters affecting the deposition process is explained, as are the various spray methods. Finally, some examples of spray pyrolysis in different applications like a gas sensor, UV photodetector, solar cell, photocatalysis, and supercapacitor are discussed.

ABSTRACTAtomic scale imaging by STM and TEM of the initial stages of film growth of Ag and Au on graphite substrates indicate that the film nucleation processes are markedly different for ionized cluster beam (ICB) and molecular beam (MBE) deposition. Recent results on measurements of cluster size and formation of epitaxial metal-semiconductor layers by ICB are also discussed.
