Electronic, elastic, and thermodynamic properties of Cd0.75TM0.25S (TM = Os or Ir) alloys with the TB-mBJ approach and hybrid density functional (HSE06)
Springer Science and Business Media LLC - - Trang 1-15 - 2023
M. Boudjelal, M. Batouche, T. Seddik, K. Bouhadjer, S. Bentata, R. Khenata, A. Belfedal, N. Badi, S. Bin-Omran
The electronic structure, elastic moduli, as well as thermodynamic features of the ferromagnetic Cd0.75TM0.25S (TM = Os or Ir) compounds in the zinc-blende phase were investigated by employing the “generalized gradient approximations” parametrized by Wu and Cohen combined with the “modified Becke-Johnson (TB-mBJ)” as well as the hybrid functional (HSE06). The predicted total magnetic moments for t...... hiện toàn bộ
Studies on structural and third order nonlinear optical properties of bulk size DAST: an interesting organic single crystal for photonic applications
Springer Science and Business Media LLC - Tập 97 - Trang 1591-1596 - 2022
M. Manivannan, A. Saranraj, S. A. Martin Britto Dhas, M. Jose
The growth of optically good quality bulk size (35 × 9 × 8 mm3) single crystal of pure 4-N, N-dimethylamino-4-N-methyl stilbazolium tosylate (DAST) crystal was reported by adopting the conventional slow evaporation solution technique. Moreover, we have found that so far nobody has detailed this enormous size DAST crystal which isn’t yet announced in the literatures. The cell dimensions of the grow...... hiện toàn bộ
Microscopic insight into molecular orbital gating
Springer Science and Business Media LLC - Tập 88 - Trang 945-950 - 2014
Saikat Mukhopadhyay, Ravindra Pandey, Shashi P. Karna
The molecular orbital gating in the 1,8-octanedithiol (ODT) and 1,4-benzenedithiol (BDT) molecules is investigated using first principles methods. The calculated I–V characteristics as a function of applied gate voltage for the σ-saturated ODT molecule are found to depend on the microscopic description of the conduction channels. On the other hand, an orbital gating in the BDT-based molecular devi...... hiện toàn bộ
Simulation optimized design of graphene-based hybrid plasmonic waveguide
Springer Science and Business Media LLC - Tập 97 - Trang 2515-2522 - 2023
A. Asadi, M. R. Jafari, M. Shahmansouri
A unique graphene-based hybrid plasmonic waveguide (GHPW) is proposed with a relatively high figure of merit (FOM) and long propagation length ( $${L}_{\mathrm{spp}}$$ ) in the far-infrared (FIR) region. The proposed waveguide is combined of a high-index cylindrical dielectric in the coordinate orig...... hiện toàn bộ
Dynamical behaviour of nonlinear structures in superthermal plasmas associated with external periodic force
Springer Science and Business Media LLC - Tập 97 - Trang 2197-2208 - 2023
Jintu Ozah, P. N. Deka
The impact of an external periodic force on the characteristics of dust ion-acoustic solitary waves in a superthermal magnetised plasma is investigated. To obtain the forced Zakharov–Kuznetsov (FZK) equation from fundamental governing equations, the well-known reductive perturbation technique is used. Furthermore, the ZK equation is transformed into planar dynamical systems to analyse the phase po...... hiện toàn bộ
Study of structural and spectroscopic behavior of Sm3+ ions in lead–zinc borate glasses containing alkali metal ions
Springer Science and Business Media LLC - Tập 91 - Trang 677-687 - 2017
M. V. Sasi Kumar, S. Babu, B. Rajeswara Reddy, Y. C. Ratnakaram
High luminescence behavior of rare earth inorganic glasses have a variety of uses in the industry. In the past few decades, rare earth ions with characteristic photonics applications are being hosted by heavy metal oxide glasses. Among the rare earth ions Sm3+ ion has features which make it apt for high density optical storage. The authors of the paper have experimented to synthesize Sm3+ doped gl...... hiện toàn bộ
Reflections on Manoj Banerjee and his early contributions to nuclear physics
Springer Science and Business Media LLC - Tập 83 - Trang 671-676 - 2009
S. Das Gupta
I highlight some of the scientific contributions of Manoj Banerjee during the years 1957 to 1969. This is more a personalised account than a complete review. Choice of material is influenced by my own bias.
Sự giảm thiểu dịch bệnh do tiếng ồn trong mô hình tự động tế bào Dịch bởi AI
Springer Science and Business Media LLC - Tập 87 - Trang 507-510 - 2013
Y. Wang, R. Z. Zhang
Trong bài báo này, chúng tôi nghiên cứu tác động của các biến đổi ngẫu nhiên không gian-thời gian cộng thêm, được giới thiệu vào tham số của một mô hình dịch tễ sử dụng tự động tế bào. Trong trường hợp không có tiếng ồn, mô hình thể hiện một chuyển pha từ trạng thái không có bệnh đến trạng thái dịch lưu hành. Tuy nhiên, chuyển pha này biến mất khi có sự xuất hiện của tiếng ồn trong mô hình. Cụ thể...... hiện toàn bộ

Role of anharmonicity binding energy on the transition dynamics of GaAs quantum dot in presence of noise
Springer Science and Business Media LLC - - Trang 1-12 - 2023
Swarnab Datta, Bhaskar Bhakti, Manas Ghosh
Present enquiry thoroughly explores the time-average excitation rate (TAER) of GaAs quantum dot (QD) pursuing the change in the anharmonicity binding energy (ABE) of the system and under the supervision of Gaussian white noise (GWN). The promotion of the ground state electronic density occurs due to various kinds of time-varying fluctuations viz. simple sinusoidal field (SSF), time-dependent confi...... hiện toàn bộ
