Design of the Nanoinjection Detectors Using Finite Element Modeling

The nanoinjection photon detectors have been developed to address the main trade-off in using nanoscale features for light detection. Even though nanoscale sensors offer high sensitivity, their interaction with visible or infrared light is severely limited by their miniscule sizes. However, due to their nonplanar design, type-II band alignment and the coupled detection/amplification mechanisms, the design and development of the nanoinjection devices required detailed nonlinear three-dimensional finite element method (FEM) simulations. The layer structure with type-II band alignment and the nonplaner geometry of nanoinjection detectors required careful design and optimization through a custom built three-dimensional nonlinear FEM simulation, which provided the mathematical groundwork to implement the stationary, parametric, and transient simulation of nonlinear differential equations. The short-wave infrared detectors play in important role in many modern world applications spanning diverse fields. The steady advancements in technology constantly increased the requirement for better and more sensitive detectors for ever more demanding applications.
