“…, here m * C and m * V are the carriers effective mass in conduction and valence bands, respectively, is the electron reduced effective mass about 0.65m e [21] for ITO. If the photon energy is equal to the B-M energy, the electron intra-band transition can take place [41] in the conduction band over the B-M barrier, which makes the ITO film to act as an ohmic conductor.…”

“…Since the energy of many-body interaction for the electron-electron and electron-ionized impurities causing narrowing of band gap is minor, the band gap energy E g for an electron transition from the top state in the valence band (with a parabolic structure [22,42]) to the lowest empty state in the semi-parabolic conduction band [41] can be obtained disregarding of this minor energy change, as [21,22,26],…”

“…So in presence of a hot electrons Fermi gas there is a transient shift in the plasma frequency and, as in the inter-band case, a shift of the ITO grating photonic band gap. The result is the ultrafast photomodulation of ITO gratings spectral response in the visible by near-IR laser pulses, very interesting since they are in the telecommunication wavelengths 32 .…”

“…A modulação de propriedades eletrônicas e controle de morfologia e tamanho de nanoestruturas por meio de métodos de sínteses é determinante para a obtenção de materiais com características únicas e de grande relevância. Materiais como óxidos transparentes semicondutores (GUIZZARDI et al, 2020a), pontos quânticos (VELA et al, 2008), compósitos (GARCÍA-FERNÁNEZ et al, 2020 e materiais híbridos (YE et al, 2014) têm sido desenvolvidos e apresentam relevante importância nesse campo.…”
