In this work, we studied the effect of electron irradiation on the structure and morphology of the surface of a single crystal and polycrystal TlIn1-xCrxS2 (x=0.01). Irradiation of a TlIn1-xCrxS2 single crystal with electrons with an energy of 2 MeV and a fluence of 2×1017 electron/cm2 leads to an increase in the maximum value of the mean arithmetic deviation of the profile from Ra=5.4 nm to Ra=25.2 nm, and also leads to an increase in the height of the average roughness from Rz=72.0 nm to Rz=152.9 nm. Irradiation of powder TlIn1-xCrxS2 with electrons with a fluence of 2×1017 electron/cm2 promotes an increase in the crystallite size from 36.87 nm to 41.76 nm, which is most likely associated with a decrease in size of the interface.

“…This is a second-order process from two zone boundary LO phonons. The G′ band is an intrinsic property of the nanotube and graphite, and present even in defect-free nanotubes for which the D band is completely absent [14]. G′ band peaks to appear at 2653 cm −1 and 2665 cm −1 for pristine and post irradiation accordingly.…”

“…The structure, topology, and size of CNTs are a source of their outstanding mechanical and optical properties and their electronic behavior. Raman spectroscopy is a valuable technique for determining the diameter distribution, chirality, purity, and architecture of CNTs [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Vibrational properties, electronic structures, quality of the samples and diameter characterization of the various carbon materials can be analyzed by the Raman spectroscopy including SWCNT, double-walled (DWCNT) [9] and multiwalled (MWCNT) carbon nanotubes [3,4,17].…”

The effect of electron irradiation up to fluence of 1.54×1017 electron/cm2 on the structural parameters, sizes of nanocrystallites, microstrains, and Raman spectra of a single-walled carbon nanotube (SWCNT) was studied. Electron irradiation leads to an increase in the lattice parameters in the a and b directions from 4.7623 Å to 4.9378 Å and a decrease along the c axis from 3.9491 Å to 3.9469 Å. Electron irradiation stimulates the growth of the nanocrystallite size from 4.06 nm to 5.03 nm, leads to a shift of the Raman spectra towards higher frequencies, and indicates the appearance of a spectrum at 805 cm–1, which is caused by the formation of defects in a SWCNT.
