Abstract

A method of determining a device behavior, wherein the method includes using a first procedure. The first procedure includes discretizing a user specified nano-device structure for at least one quantum method. Additionally, the first procedure includes solving the at least one quantum method, thereby having a solution of the at least one quantum method. Moreover, the first procedure includes extracting a parameter out of the solution of the at least one quantum method. Next, the first procedure includes applying at least one approximate method to the user-specified nano-device structure using the parameter. The first procedure additionally includes solving the at least one approximate method to the user-specified nano-device structure using the parameter. The first procedure also includes extracting the device behavior of the user-specified nano-device structure. Next, the method of determining the device behavior includes iterating the first procedure until a condition is satisfied.

Dependent claims

A non-transitory computer-readable medium encoded with a computer readable program, which, when executed by a processor, causes a computer to execute a method of determining a device behavior, wherein the method comprises:

(A) using a first procedure, wherein the first procedure comprises:
(i) discretizing a user specified nano-device structure for a full scale quantum method;
(ii) solving the full scale quantum method, thereby having a solution of the full scale quantum method;
(iii) extracting a parameter out of the solution of the full scale quantum method;
(iv) applying an approximate method to the user-specified nano-device structure using the parameter;
(v) solving the approximate method to the user-specified nano-device structure using the parameter;
and
(vi) extracting the device behavior of the user-specified nano-device structure;
and
(B) iterating the first procedure until a condition is satisfied,
wherein the condition comprises at least one of:
the parameter remains constant, a change in the parameter is smaller than a user specified limit, a change in the device behavior is smaller than the user specified limit, the parameter has reached a specific value, or the device behavior has reached a user specified characteristic, and
wherein the approximate method includes different equations or methods than the full scale quantum method.
