Kinetics of photostimulated transformations in nanosized bismuth films

Kinetic regularities of thermal transformations in nanosized lead films

“…The samples were prepared for studies by deposit ing thin (2-115 nm) lead films on glass substrates by thermal evaporation in vacuum (2 × 10 -3 Pa) using a VUP 5M vacuum system [24][25][26]. The substrates were glass photo plates (State Standard GOST 9284 59), which were preliminarily treated in concentrated nitric acid, potassium dichromate solution, concen trated sulfuric acid, and boiling surfactant solution; washed in distilled water; and dried [24][25][26].…”

“…The substrates were glass photo plates (State Standard GOST 9284 59), which were preliminarily treated in concentrated nitric acid, potassium dichromate solution, concen trated sulfuric acid, and boiling surfactant solution; washed in distilled water; and dried [24][25][26]. The treated substrates were optically transparent in the range 300-1100 nm.…”

“…Nanosized and submicron metal and metal oxide films and multilayer film heterosystems are now being widely used as design elements and functional layers in modern electronic devices and parts of aerospace structures and as solid wear resistant coatings in pro cessing industry [1][2][3][4][5][6][7][8][9]. Lead is also widely used in var ious fields of science, technology, and industry due to its useful properties (plasticity, low melting point, cor rosion resistance, etc.)…”

Kinetic laws of thermal transformations in nickel nanofilms

“…Studies of the laws governing processes that occur in nanolayers of various materials under the action of different energy factors are of interest to both solid state physics and chemistry and in the development of real systems with adjustable levels of sensitivity to var ious external impacts [1][2][3][4][5][6][7][8][9]. Due to their set of useful properties (e.g., corrosion resistance, high plasticity and ductility, chemical inertness, heat resistance, strength, magnetostriction, the ability to dissolve sig nificant amounts of other metals, and low vapor pres sure), nickel and compounds based on it are exten sively used in many fields of science, engineering, and industry [10][11][12][13][14][15].…”

“…EXPERIMENTAL Test samples were prepared by depositing thin nickel layers (3-60 nm) via thermal evaporation in a vacuum (2 × 10 -3 Pa) on glass substrates using a VUP 5M multipurpose vacuum station [22][23][24]. The substrates were prepared on the glass of photographic plates (GOST 9284 59) pretreated in concentrated nitric acid, a potassium dichromate solution in con centrated sulfuric acid, and boiling soapy water and then washed in distilled water and dried [22][23][24].…”
