Synthesis of 2D yttrium zinc oxide nanosheets via simple chemical route toward high performance Schottky diode based on large charge carriers density and photoresponsivity

“…In this equation, q denotes the carrier charge is constant value equals 1.6 10 C, 19 ´k is the Boltzmann constant given by the value 1.38 10 kg m s K , ´--and T is the absolute temperature was 300 Kelvin. The electronic parameters including potential barrier , b f reverse saturation current I , s and ideality factor n have been identified in the forward biased at low voltage 0 V 0.4.…”

“…b respectively[19,20]. Where, β signifies the full width at half maximum (FWHM) of the corresponding peak measures in radians, k represents the proportionality constant known as shape factor equals 0.94, θ is the Bragg's scattering angle, and λ denotes the wavelength of x-ray (λ = 1.541 Å for CuK α radiation).…”

Aloe vera assisted green synthesis of Ag and Cu co-doped ZnO nanoparticles and a comprehensive analysis of their structural, morphological, optical, electrical and antibacterial properties

“…Co-doping with Ni & Cu [ 65 ], Y & Cu [ 66 ], and Al & Cu [ 67 ] show higher dielectric constant, ferromagnetism, and better optical properties suitable for optoelectronic device development. On the other hand, co-doping ZnO nanoparticles with Al & Ag [ 68 ], Ni & Ag [ 69 ], and Y & Ag [ 69 ] have been observed to have better electrical, optical, and photocatalytic properties.…”
