Witryna7 kwi 2015 · In this work, we first studied the dependence of carbon impurity concentration in AlGaN layers on growth conditions such as growth temperature, growth pressure, and growth rate. Then, Hall measurements were carried out to study the effect of carbon concentration on the electrical conductivity in AlGaN layers with an Al … Witryna2 mar 2024 · Resistivity is the opposite of electrical conductivity, evaluating how strongly a metal opposes the flow of electric current. This is commonly measured across the opposite faces of a one-meter cube of material and described as an ohm meter (Ω⋅m). Resistivity is often represented by the Greek letter rho (ρ).
