A highly ordered structure and a relatively simple method of obtaining porous anodic alumina (PAA) have been attracting the attention of researchers to the potentialities of using such material in various fields of science and technology. The PAA-technology is oriented to mass production, does not require the use of expensive modern lithography and evaporation equipment. The technology makes it possible to produce PAA layers in a wide thickness range (0.1 -800 μm) and with a spatially ordered system of pores whose diameter and periodicity can be changed within the range from tens to hundreds of nanometers. By filling nanopores with conductive, semiconductive and dielectric materials or their combinations, possibilities arise of making micro-sensors based on various physical, chemical and biological effects. For numerous applications, there is a promising development direction associated with modification of PAA structures with nano-diamonds. To control the modification process and for subsequent use of films in energyabsorbing sensor systems, a real-time measurement is required of their thermal and physical parameters, and, in particular, the coefficient of thermal diffusion (CTD).In this report an optical method for determining CTD is developed which is based on an analysis of the spatialtemporal dynamics of the speckle field. The proposed method for measuring the coefficient of thermal diffusion is based on the measurement of an average speed of the speckle-field movement along the specimen surface. Due to statistical nature of speckles, their movement must be also described statistically. Our approach consists in the use of correlation functions describing the degree of change in a speckle-image of some element of the surface in the process of heating or cooling. The proposed method is fully optical, fast, non-invasive and can be customized for specific applications. Optical measurement of CTD has been carried out for PAA structures both modified and not modified with nano-diamonds. High resolution allows one to measure spatial inhomogeneities of thermophysical properties of PAA-films.

“…In this case the peculiarity of formation of thick layers of AA (over tens of micrometers) is the creation of regular nanoporous structures. The presence of nanoporous while using 3D substrates in vacuum integrated circuit (VIC) based on thermoemitters is a significant disadvantage [4]. Purposeful technological processing significantly reduces its negative effect on output characteristics of VIC.…”

Herein we are offering a concept of matrix FE devices construction based on alumina technology opportunities combined with nanocarbon diamondlike materials and classical microdisplay construction. FE matrix cathode contains a massive of spikes with the emitting part in the form of NCT grown with the help of CVD method. The function of centers is fulfilled by ends of nanospikes formed by the metallization of periodical transparent nanoporous passing in substrates from one of anodic alumina (AA) surface. Spikes are grouped in separate plaits forming periodical grid. On the backside of the grid there is a resistive layer made of thin diamondlike nanomaterial and above it there is a conductive layer on each of the spikes. Control grid is formed in the way of monolith with controlling electrode 3D substrate. Dielectrical lugs on the substrate fulfill the function of spacers 1 and with high precision they keep the distance between cathode and grid while assembling microtriode. To provide precise distance between grid and anode as spacers 2 a frame made of AA and of a certain thickness is used. Modeling of triode systems with FE and separate controlling structures made of AA showed high efficiency of such a classical construction.
