Application of Aloe vera gel instead of silicon dioxide as organic dielectric material in microelectronics

Abstract

Organic materials are now being used in a wide range of microelectronic applications in parallel with inorganic materials, because of their superior properties, environmental safety, and low cost. This paper describes the characterization of Aloe vera gel (AVG), a new organic dielectric material. The surface morphology, spatial distribution of elements, and structural characteristics of an AVG layer were examined using scanning electron microscopy, energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD), respectively. The resistance of the AVG layer, determined using a four-probe station, was 640 Ω. EDX showed that the elements contained in the layer were carbon, oxygen, aluminum, silicon, calcium, potassium, and copper. The XRD results suggested that the sample primarily consisted of bornite (Cu 5 FeS 4 ), geerite (Cu 8 S 5 ), sal ammoniac (NH 4 Cl), and carobbite (KF).

Facile Synthesis of Antimicrobial Aloe Vera-“Smart” Triiodide-PVP Biomaterials

“…Ray et al [ 52 ] investigated the EDS of Aloe vera barbadensis Miller, and reported Na, Mg, K, Ca, Cd, Al and P, with the two latter minerals in negligible amounts. Rana et al found in their EDX analysis Al, K, Ca, Si, P and Cu in decreasing weight percentages [ 71 ]. The elemental distribution in AV depends highly on soil, location, climate and harvest season [ 52 ].…”
