Molybdenum diselenide (MoSe2)/silicon (Si) heterostructures hold promise for advanced devices with improved performance, especially broadband photodetectors a fast response. In this study, we investigate the impact of growth temperature on ultrathin MoSe2 films grown Si(111) substrate using molecular beam epitaxy. The in range 450 to 550 °C is explored. 500 found be optimum crystalline and uniform films. quality thoroughly examined techniques such as reflection high-energy electron...
Abstract Despite advancements in terahertz (THz) modulators, achieving a balance between large modulation depth (MD) and fast speed scalable devices remains significant challenge. Optically pumped THz modulators with high MD, broad bandwidth, response times are essential for progress technology. Here, MoTe 2 /Si van der Waals (vdW) heterostructures grown via molecular beam epitaxy (MBE) as an optically leveraging its favorable band alignment seamless integration silicon complementary...
Gallium telluride thin films have emerged as a promising material for various electronic and optoelectronic applications due to their unique properties. In this study, we investigate the growth of nanometer-thick GaTe on sapphire substrates using molecular beam epitaxy explore influence temperature structural, electronic, optical properties films. X-ray diffraction, scanning electron microscopy, photoelectron spectroscopy, Raman measurements are employed characterize structural quality...
The polymorphic nature of ultrathin transition metal dichalcogenide (TMDC) materials makes the phase engineering these an interesting field investigation. Understanding phase-controlling behavior different growth parameters is crucial for obtaining large-area a desirable phase. Here, we report detailed study on effect phases few-layer MoTe
Variation of refractive index ( n ) with photon energy and current I voltage V for different thicknesses MoSe 2 films has been reported. The layer-dependent band diagram shows n-type conductivity 1L to 7L films.
MoTe2, a two-dimensional (2D) transition-metal dichalcogenide, has recently gained significant attention due to its unique optical and electronic properties. In this research paper, we present the transition of 2H 1T′ phase MoTe2 films by controlled growth using molecular beam epitaxy. Raman spectroscopy confirms phases MoTe2. Then, extensively study properties having variable nanodimensional thicknesses spectroscopic ellipsometry (SE). SE is powerful technique for characterizing thin films,...

Ethno-medicinal studies were carried out during last five years in eleven tribal dominated districts of Chatra, Deoghar, Dumka, Giridih, Godda, Jamtara, Koderma, Saraikela Kharsawan, Pakur, Ranchi and West Singhbhum Jharkhand, India. A total 105 informants including 30 local folk healers (Vaidyas, Kaviraj Bhagat) belonging to communities, who had knowledge the traditional uses medicinal plants, interviewed for gathering information. The study led documentation therapeutic application 98...
In the present study, molecular diversity among 38 accessions of holy basil (Ocimum tenuiflorum) collected from four phyto-geographical regions India was assessed using RAPD and ISSR markers. A total 80 fragments were amplified with 19 selected primers (4.21 per primer), which 66 (82.50%) polymorphic. The resolving power (Rp) for ranged 2.32 to 8.96 an average 5.48 primer. Similarly, nine a 25 scorable (2.77 primer) out 18 (72.00%) Rp ISSRs 2.4 (UBC-807) 9.95 (UBC-886). For genetic...
Andrographis paniculata (Burm.f.) Wall. ex Nees (family-Acanthaceae) popularly known as Kalmegh (Hindi), is an important medicinal herb used in different ayurvedic formulations India. A total of 155 accessions have so far been collected by National Bureau Plant Genetic Resources (NBPGR) mainly from parts Chhattisgarh, Madhya Pradesh, Odisha and Uttar Pradesh. Among these, forty four were grown for characterization, evaluation identification trait-specific germplasm using nine quantitative...
