Electronic structure calculations reveal indirect band gaps of 2.55 eV for In₂S₂, 2.44 eV for In₂Se₂, and 2.22 eV for In₂Te₂, demonstrating a systematic narrowing along the S→Se→Te sequence. Further, work functions decrease correspondingly from 6.334 to 6.047 to 5.575 eV across the S→Se→Te series. Optical analysis up to 15 eV reveals that In₂Te₂ exhibits maximum reflectivity exceeding 0.35 at ∼4 eV, the highest refractive index (n ≈ 2.5), and the strongest plasmon-loss peak at ∼9.5 eV, whereas In₂S₂ achieves a maximum absorption peak at 6 eV with minimal optical losses.

This work presents a theoretical study of electron transport in monolayer MoS₂ using a multi-orbital tight-binding (TB) model and the non-equilibrium Green's function (NEGF) formalism. The TB Hamiltonian, fit to reproduce the first-principles band structure, is implemented in a quantum transport code to simulate a two-terminal MoS₂ device. The electronic band structure and density of states are calculated using the multi-orbital tight-binding framework, and the transport behavior is analysed through energy-dependent transmission spectra, temperature-dependent current–voltage characteristics, and field-effect mobility. The NEGF method is further used to investigate how atomic defects affect conductance. Our results show a direct band gap at the K-point, thermally activated transport behavior, mobility degradation at elevated temperatures, and a strong suppression of conductance by atomic vacancies.

This design homogenizes the atomic spin polarization distribution and suppresses light shifts and power broadening. This uniform polarization, in turn, allows the five-pass probe configuration to achieve a significantly larger signal amplitude.
