In India around 8.8% of the total population consist of tribal. They are of primitive human civilisation of India. The major tribes in India are the Gonds, the Bhils, the Santals, the Oraons, the Minas and the Mundas. Eighty percent of the tribes are found in the central region of India. If we look back in the history of pre-independent India, the tribes’ position was not in much privileged; they are intended for the laborious job, a kind of slaves under the British colonials. Later on, a decade of independence, unfortunately there are virtually no alterations in the present socio-economic scenario of the tribe’s conditions. Tribes are treated as outsiders and unwanted in their own homeland by the modern capitalist’s society. In the process of national development tribes and their cultural identity is badly affected as compared to any other community as the second Five Year Plan was modelled on the idea of either industriali...

Here, we grow nanolaminate Ti 3 AlC 2 thin films by pulsed laser deposition on c-axis-oriented sapphire substrates and, surprisingly, the films are found to be highly oriented along the (103) axis normal to the film plane, rather than the (000l) orientation. Multiple characterization techniques are employed to explore the structural and chemical quality of these films, the electrical and optical properties, and the device functionalities. The 80-nm thick Ti 3 AlC 2 film is highly conducting at room temperature, with a resistivity of about 50 µ cm and a very-low-temperature coefficient of resistivity. The ultrathin (2 nm) Ti 3 AlC 2 film has fairly good optical transparency (∼70%) and high conductivity (sheet resistance ∼735 /sq) at room temperature. Scanning tunneling microscopy reveals the metallic characteristics (finite density of states at the Fermi level) at room temperature. The metal-semiconductor junction of the p-type Ti 3 AlC 2 film and n-Si show the expected rectification (diode) characteristics, in contrast to the ohmic contact behavior in the case of Ti 3 AlC 2 /p-Si. A triboelectric-nanogenerator-based touch-sensing device, comprising of the Ti 3 AlC 2 film, shows a very impressive peak-to-peak open-circuit output voltage (∼80 V). These observations reveal that pulsed laser deposited Ti 3 AlC 2 thin films have excellent potential for applications in multiple domains, such as bottom electrodes, resistors for highprecision measurements, Schottky diodes, ohmic contacts, fairly transparent ultrathin conductors, and next-generation biomechanical touch sensors for energy harvesting.
