Applications of Heterostructure Design Studio

Optoelectronic device engineering
Design of optoelectronics devices requires costly preparation of samples to get desired properties. The Heterostructure Design Studio allows predicting device properties by doing simulation. The calculations of wave functions, momentum matrix elements, optical gain etc with different input parameters of heterostructure provides the necessary information about device properties and its behavior under different external conditions that decreases the device design time and costs. Engineers involving in designing of semiconductor heterostructure devices will find the Heterostructure Design Studio an extremely helpful tool.
Theoretical studies of novel
heterostructures in research labs and universities
The Heterostructure Design Studio provides scientists with precise and accurate calculations during all steps of heterostructure simulation. Knowledge of bandstructure calculated according to precise model and optical properties allows to work not only with novel structures but also to find hidden features properties in already known structures. Both scientists doing theoretical and experimental research will find the Heterostructure Design Studio an indispensable tool for their work.
Quantum mechanics training in semiconductor
heterostructure studies at universities
Semiconductor heterostructures are subjects of study at quantum mechanics university courses. The base of courses is the theory of band structure and wave functions. Due to extremely complicated formulas, which include eigenvalue and eigenfunction problem of differential equations' system, it is impossible to get a result in analytical expressions. The Heterostructure Design Studio can be a working tool in solving exercises for the chapters in textbooks related to theory of heterostructures. Use of Heterostructure Design Studio provides students with both deep understanding of theory and practice in heterostructure calculations.
