The high K anomaly in ScAlN explained
Ilan Shalish
The integration of scandium aluminum nitride (ScAlN) into functional heterostructures has pushed semiconductor device physics into an extreme piezoelectric regime. Accurately deter…
NO2 adsorption on GaN surface and its interaction with the yellow-luminescence-associated surface state
Yury Turkulets, Nitzan Shauloff, Or Haim Chaulker +2
Trapping of charge at surface states is a longstanding problem in GaN that hinders a full realization of its potential as a semiconductor for microelectronics. At least part of thi…
Is the Mg-related GaN blue luminescence deep-level an MgO surface state?
Or Haim Chaulker, Yury Turkulets, Ilan Shalish
Mg is currently the only p-type dopant in technological use in GaN. Its incorporation into the GaN lattice is difficult. It requires a thermal treatment that only partially activat…
Homologous self-assembled superlattices: What causes their periodic polarity switching? Review, model, and experimental test
Varun Thakur, Dor Benafsha, Yury Turkulets +4
Quantum semiconductor structures are commonly achieved by bandgap engineering that relies on the ability to switch from one semiconductor to another during their growth. Growth of…
The GaN yellow-luminescence-related surface state and its interaction with air
Yury Turkulets, Nitzan Shauloff, Or Haim Chaulker +3
Yellow luminescence (YL) is probably the longest and most studied defect-related luminescence band in GaN, yet its electronic structure or chemical identity remain unclear. Most of…
Polar charge induced self-assembly: An electric effect that causes non-isotropic nanorod growth in wurtzite semiconductors
Yury Turkulets, Ilan Shalish
Crystals grow by gathering and bonding of atoms to form an ordered structure. Typically, the growth is equally probable in all crystalline directions, but sometimes, it is not, as…
Why do nanowires grow with their c-axis vertically-aligned in the absence of epitaxy?
Almog R. Azulay, Yury Turkulets, Davide Del Gaudio +2
Images of uniform and upright nanowires are fascinating, but often, they are quite puzzling, when epitaxial templating from the substrate is clearly absent. Here, we reveal the phy…
