Compact and efficient power electronics with applications to solar PV, automotive, and aerospace systems
… ZVS minimizes switching losses and enables high-frequency operation of the converter. The flexible nature of the board enables the converter to be integrated to non-flat surfaces such as motors, pipes, or airfoils. Another such application is the minimization of size and weight of the power stage …

Nonlocal ballistic and hydrodynamic transport in two-dimensional electron systems
… We apply the non-linearity to rectification and frequency multiplication. We also report on a periodic peaks in the nonlocal voltage vs. magnetic field, in an enclosed mesoscopic geometry in which transverse magnetic focusing (TMF) is typically studied. These peaks occur at weak magnetic fields, …
