A semiconductor film includes a cluster of semiconductor quantum dots each having a metal atom and ligands coordinating to respective semiconductor quantum dots, and the semiconductor quantum dots have an average shortest inter-dot distance of less than 0.45 nm. A solar cell, a light-emitting diode, a thin film transistor, and an electronic device include the semiconductor film.

Semiconductor film, solar cell, light-emitting diode, thin film transistor, and electronic device

A semiconductor film, including: an assembly of semiconductor quantum dots containing a metal atom; and a ligand that is coordinated to the semiconductor quantum dots and that is represented by the following Formula (A): wherein, in Formula (A), Xrepresents NH, S, or O; each of Xand Xindependently represents NH, SH, or OH; and each of n and m independently represents an integer from 1 to 3.

Semiconductor film, method of producing semiconductor film, solar cell, light-emitting diode, thin film transistor, and electronic device

A semiconductor film, including: an assembly of semiconductor quantum dots containing a metal atom; and at least one ligand that is coordinated to the semiconductor quantum dots and that is selected from a ligand represented by Formula (A), a ligand represented by Formula (B), and a ligand represented by Formula (C): wherein, in Formula (A), Xrepresents &#x2014;SH, &#x2014;NH, or &#x2014;OH; and each of Aand Bindependently represents a hydrogen atom or a substituent having from 1 to 10 atoms; provided that when Aand Bare both hydrogen atoms, Xrepresents &#x2014;SH or &#x2014;OH; in Formula (B), Xrepresents &#x2014;SH, &#x2014;NH, or &#x2014;OH; and each of Aand Bindependently represents a hydrogen atom or a substituent having from 1 to 10 atoms; and in Formula (C), Arepresents a hydrogen atom or a substituent having from 1 to 10 atoms.
