Theory
On this page, we present the fundamental theoretical models that underpin QTCAD.
In Section 1 to Section 9, we describe the mathematical models defining each solver in the device simulator, along with physical quantities that can be calculated using these solvers.
In Section 10 and Section 11, we consider the theoretical concepts that underlie the transport simulator.
Finally in Section 12, we describe the theory behind the qubit simulator.
