Aerosol deposition technology and its applications in batteries

Aerosol deposition(AD)method is a kind of additive manufacturing technology for fabricating dense films such as metals and ceramics at room temperature.It resolves the challenge of integrating ceramic films onto temperaturesensitive substrates,including metals,glasses,and polymers.It should be emphasized that the AD is a spray coating technology that uses powder without thermal assistance to generate films with high density.Compared to the traditional sputter-based approach,the AD shows several advantages in efficiency,convenience,better interfacial bonding and so on.Therefore,it opens some possibilities to the field of batteries,especially all-solidstate batteries(ASSBs)and draws much attention not only for research but also for large scale applications.The purpose of this work is to provide a critical review on the science and technology of AD as well as its applications in the field of batteries.The process,mechanism and effective parameters of AD,and recent developments in AD applications in the field of batteries will be systematically reviewed so that a trend for AD will be finally provided.

A review on polishing technology of large area free-standing CVD diamond films

Recently,with the rapid development of chemical vapor deposition(CVD)technology,large area free-standing CVD diamond films have been produced successfully.However,the coarse grain size on the surface and the non-uniform thickness of unprocessed CVD diamond films make it difficult to meet the application requirement.The current study evaluates several existing polishing methods for CVD diamond films,including mechanical polishing,chemical mechanical polishing and tribochemical polishing technology.

Effect of pressure on the electrical properties of flexible NiPc thin films fabricated by rubbing-in technology

Nickel phthalocyanine(Ni Pc) film was deposited onto the surface of flexible conductive glass by rubbing-in technology and used to fabricate devices based on ITO/Ni Pc/CNT/rubber structure. The I–V characteristics of the devices were investigated under different uniaxial pressures of 200, 280, and 480 gf/cm^(2), applied perpendicular to the surface of the Ni Pc film. Results showed that the nonlinearity coefficients of the I–V curves are in the range of 2 to 3, which was found to be decreased with the increase of the pressure. The rectification ratio of the devices was estimated to be varied from 1.5 to 3 based on the applied pressure. Concluding, the resistance of the active layers was decreased with the increase of both pressure and voltage. We believe that using the rubbing-in technology under sufficient applied pressure it is possible to utilize Ni Pc for the development of various electronic devices such as diodes, nonlinear resistors, and sensors.

The Challenges of Microelectronics for the Future Digital Society: The Roles of Thin Film Technologies and of the Higher Education

The new digital society is based on Internet of Things (IoT) and related connected objects are becoming more prevalent around the world. This evolution implies innovation in many areas of technology, the heart of which is microelectronics. Connected objects involve many technological components and functions that are directly dependent of the microelectronics capabilities. If the perspectives are exciting, several challenges are appearing. The first is related to the energy consumption of all these objects, which will become enormous by 2030, and unrealistic by 2040. The second is human resources concern. The future engineers and PhD will have many obstacles to overcome. A way to face these challenges is to involve more and more new thin film technologies that must be combined with VLSI ones, and to better train students to this domain with enough know-how and with a large spectrum of knowledge suitable for multidisciplinary applications. The French national network for Higher Education in microelectronics has adopted this strategy. After presentation of the challenges, this paper deals with the innovative activities of the French network focused on thin film technologies, in order to face the challenges in a short future.
