Films of n-Hg0.775Cd0.225Te with near-surface wide-gap layers were grown by molecular beam epitaxy on Si (013) substrates. To measure the admittance, metal – insulator – semiconductor (MIS) structures were fabricated on the basis of the as-grown HgCdTe film, films after implantation, and films after implantation and annealing. Using techniques that take into account the presence of graded-gap layers and slow interface states, the main parameters of the near-surface layers of HgCdTe films have been determined after the technological procedures used to create photodiodes.

Information on localized states at the interfaces of solution-processed organic semiconductors and polymer gate insulators is critical to the development of printable organic field-effect transistors (OFETs) with good electrical performance. This paper reports on the use of impedance spectroscopy to determine the energy distribution of the density of interface states in organic metal-insulator-semiconductor (MIS) capacitors based on poly(3-hexylthiophene) (P3HT) with three different polymer gate insulators, including polyimide, poly(4-vinylphenol), and poly(methylsilsesquioxane). The findings of the study indicate that the impedance characteristics of the P3HT MIS capacitors are strongly affected by patterning and thermal annealing of the organic semiconductor films. To extract the interface-state distributions from the conductance of the P3HT MIS capacitors, an equivalent circuit model with continuum trap states is used, which also takes the band-bending fluctuations into consideration. In addition, the relationship between the determined interface states and the electrical characteristics of P3HT-based OFETs is investigated.
