Electrical Properties in Ta2NiSe5 Film and van der Waals Heterojunction

Ternary Ta2NiSe5 is a novel electronic material having the property of an excitonic insulator at room temperature. The electrical properties of Ta2NiSe5 have not been elucidated in detail. We discuss the electronic properties in Ta2NiSe5 films and the formation of heterojunctions. Hall effect measurements showed p-type conductivity. The activation energies estimated from the temperature dependence of the carrier concentration were seen to be 0.17 eV and 0.12 eV, at approximately 300 and 400 K, respectively. It was observed that carrier generation behavior changes at the critical temperature of the excitonic insulator state (328 K). The temperature dependence of the Hall mobility below the critical temperature nearly follows the bell-shaped curves for conventional semiconductor materials. A MoS2/Ta2NiSe5 van der Waals heterojunction was fabricated using the transfer method. Rectification characteristics, which depend on the gate bias voltage, were obtained. The barrier height at the MoS2/Ta2NiSe5 heterointerface and the on/off ratio could be modulated by applying a gate bias voltage, suggesting that the carrier transport was exhibited in band-to-band flow. Our demonstration suggests that the knowledge of Ta2NiSe5 increased as an electronic material, and diode performance was successfully achieved for the electronic device applications.

The Effect Of Styrofoam As An Additive In Laston Lapis Aus Mixture

Styrofoam is waste from the disposal of electronic material buffers. This waste can be found in several main places in electronic store warehouses. This study aims to determine the value of the characteristics of the mixture of Laston Lapis Aus the effect of Styrofoam as an additive on the characteristics of the mixture of Laston Lapis Aus which uses the Malili river aggregate and Styrofoam as an added material through testing. The method used is the Conventional Marshall Method which tests and analyzes the characteristics of the mixture. The results showed the characteristics of the Laston Lapis Aus mixture using Malili River Stone and Styrofoam as added materials. Through Marshall test testing, the mixed characteristic values, namely stability, flow, VIM, VMA, and VFB all met the General Specifications of Highways 2018. The effect of adding Styrofoam to the mixture Laston Lapis Aus is able to fill voids in the mixture which makes the voids smaller, making the bonds between the aggregates stronger so that with the addition of Styrofoam the mixture becomes more water-resistant/resistant to water, weather and traffic loads.

Spectroscopic Investigation of Polyaniline Co Poly Meta Amino Benzene Sulfonic Acid

Similar to metals, conducting polymers possess an extraordinary ability to conduct electricity due to their intrinsic properties. There has been considerable focus on the synthesis and development of such materials for a wide variety of applications. In this regard, polyaniline and its derivatives have versatile applications including use as active electronic material, fabrication of modified electrode, sensors, in secondary batteries and in microelectronic and electrochromic device. Introduction of potential polymers like PAN and PPY or PTF as conductive co-polymer, interpenetrating network or blends would be a challenging step towards the preparation of novel and cheap material with modified antistatic properties. In this work we used poly (m-amino benzene sulfonic acid) and poly aniline for the preparation of composite. Aniline and m-amino benzene sulfonic acid can be fast polymerized in water to yield conducting nano composites. The composites were easily water dispersable and showed prolonged stability. <br><br><br>
