A vehicle may include a controller configured to control the vehicle to operate in an active control mode or a passive control mode. In the passive control mode, the controller may provide a feedback indicator on a human machine interface. In the active control mode, the controller may provide a control command to an engine control unit.

This work describes the recent development of Dynamic Hydride Vapor Phase Epitaxy (D-HVPE), which extends the standard HVPE process to allow for the deposition of relatively complex heterostructures and devices at growth rates in excess of 300 um/h. This process uses low-cost elemental metal precursors, and uses all of the reactants efficiently to create high-performance devices. D-HVPE also lends itself to potential in-line growth, which when combined with the low-cost precursors and extremely fast growth rates for high-quality III-V materials, can lead to significantly lower epitaxial growth costs. Here, we focus on the growth of high-efficiency photovoltaics as an example device to show the capabilities of the D-HVPE growth process.
