ABSTRACT
In this theoretical study, the electron emission from a copper surface under ultrashort pulsed laser irradiation is investigated using a one-dimensional particle in cell model. Thermionic emission as well as multiphoton photoelectron emission were taken into account. The emitted electrons create a negative space charge above the target; consequently the generated electric field reduces the electron emission by several orders of magnitude. The simulations indicate that the space charge effect should be considered when investigating electron emission related phenomena in materials under ultrashort pulsed laser irradiation of metals.

    We report the mechanism of current injection in (Ni/Au)/p-AlxGa1-xN:Mg(0≤x<0.1) Ohmic contacts based on the temperature dependence of hole concentrations (p) and specific contact resistance (ρc). The injection mechanism is found to be thermionic emission in all cases. A model is...

    We demonstrate the formation of semimetal graphite/semiconductor Schottky barriers where the semiconductor is either silicon (Si), gallium arsenide (GaAs), or 4H-silicon carbide (4H-SiC). Near room temperature, the forward-bias diode characteristics are well described by thermionic emission, and...

    The current-voltage characteristics of the Ni/InAlN/GaN Schottky diodes were measured at various temperatures in the range of 300–700 K. The experimental data were analyzed considering different current-transport mechanisms. From the analysis it follows that the tunneling current, which...

    The open-circuit voltage (Voc) of bulk heterojunction solar cells based on polymers and fullerene derivatives is limited to ∼1.15 V by the optical band gap of the fullerene of ∼1.75 eV and the required 0.6 eV offset for efficient charge generation. In practice this limit has not yet...
