Designing a Robust Kelvin Probe Setup Optimized for Long-Term Surface Photovoltage Acquisition [PDF]

Sensors, 2018
We introduce a robust low-budget Kelvin probe design that is optimized for the long-term acquisition of surface photovoltage (SPV) data, especially developed for highly resistive systems, which exhibit—in contrast to conventional semiconductors ...

Dipolar modulation of surface states in GaN via molecular ionization energy [PDF]

Scientific Reports
Gallium nitride (GaN) surface states play a pivotal role in determining device performance and stability. Here, we show that adsorption of molecules with varying ionization energies modulates GaN surface states, as revealed by surface photovoltage and X ...

Ag Nanowire‐Integrated MoS2/ZnO Heterojunctions for Highly Efficient Photogenerated Charge Transfer

Advanced Electronic Materials
The integration of silver nanowire (AgNW) networks with MoS2/ZnO heterojunctions leads to a remarkable enhancement in surface photovoltage (SPV) response. In the visible wavelength range, the heterojunctions with AgNWs achieve an SPV signal of ≈200 mV, a

The Mg related GaN blue luminescence deep level and its connection to an MgO surface state [PDF]

Scientific Reports
GaN is taking over from silicon in power electronics, but its density of interface states has yet to be adequately controlled. The major step turning GaN into a technological semiconductor was its p-type doping.
