Abstract

Tunneling current in bipolar transistors Si/Si1-xGex/Si anisotropic hetero structure for germanium conditions on a constant basis is not analyzed here. The concentration of germanium in the base which is not constant will result in the potential profile at the base is not flat, but will be graded according to the germanium concentration. Tunneling current calculation is performed semi-analytically and numerically. The calculation result obtained then matched with experimental data. The results show that the results of analytical calculations with results of semi-numerical calculations. While analytical calculations with experimental data only flows from the VBE 0.3 to 0.6 V.   Keywords: Tunneling current, germanium concentration, anisotropic material, transfer matrix method, hetero structure bipolar transistor

Abstract

It was fabricated a composite using solid waste as filler and polyvinyl acetate (PVAc) as matrice. This work is as a solution of more serious solid waste problems. The solid waste used is paper waste and leaf one with their composition are 60% and 40% respectively. The crushed-solid waste then hot-pressed at 100 MPa of pressure and 150°C of temperature. Then, the compressive strength of composite before and after PVAc presence was investigated to get a composition in which the compressive strength is optimum.   Keywords: composite, solid waste, polyvinyl acetate, compressive strength.
