Herein, films of barium antimonides (BaSb) are fabricated by a thermal deposition technique under vacuum pressure 10 −5 mbar. BaSb exhibit orthorhombic lattice. Over wide range scans, the mostly stoichiometric, displaying atomic contents 50.17 and 49.83 at% for Ba Sb, respectively. Morphological analyses these show growth large grains with sizes ranging from 1.64 to 4.14 μm. Dynamic electrical measurements on Ag/BaSb/Ag conducted in frequency domain 0.01–1.80 GHz. The display features voltage‐controlled negative capacitance source (VCNC) resonance–antiresonance peaks at critical Lorentz models spectral indicate that they correspond high‐frequency value 2.8 nF, density oscillators 4 × cm −3 , scattering time constant τ = 100 ns. Additionally, variety cutoff spectra, making them suitable applications. varies 2.6 GHz 1.0 THz as driving increases VCNC sources, behavior, high make thin promising thin‐film transistors 6 G technology
