摘要: Compositions and mechanisms for the transfer of spin-triplet excitons from a singlet exciton fission material (e.g., tetracene) to an inorganic semiconductor (e.g., n-doped silicon) are provided. The compositions include one or more interlayers, including a charge transfer interlayer (e.g., zinc phthalocyanine), and, optionally, a passivation interlayer (e.g., hafnium oxide, HfO2). The triplet transfer mechanism proceeds via the formation of a charge transfer intermediate state. The transition to the intermediate state is energetically favored by strategically positioned HOMO and/or LUMO levels of the charge transfer interlayer between the singlet fission layer and the inorganic semiconductor. The intermediate state is formed through a transition of either the electron or the hole of the triplet exciton in the charge transfer interlayer (depending, at least in part, on the relative positions of the energy levels) to the conduction or valence band of the inorganic semiconductor, respectively. Methods of forming the compositions are also disclosed.

摘要: A cooled power module package (100) comprises: a power module (110) with an upper metal layer forming an upper heat dissipation surface (111a); a heat sink (120) comprising a heat absorption surface (121b); a metal substrate (130) enclosed between the heat absorption surface and the upper heat dissipation surface. The metal substrate comprises first metal threads (132a) protruding from a first substrate side (131a) of the metal substrate towards the heat absorption surface. The first metal threads are arranged within a first cavity formed within a surface structure of the heat absorption surface of the heat sink. The metal substrate comprises second metal threads (132b) protruding from a second substrate side (131b) of the metal substrate towards the upper heat dissipation surface of the power module. The second metal threads are arranged within a second cavity formed within a surface structure of the upper heat dissipation surface of the power module.

摘要: An electronic device includes an integrated circuit package including a die mounted on a die carrier, a mold structure at least partially encapsulating the mounted die, and a heat transfer chimney formed on the die. The heat transfer chimney extends at least partially through the mold structure to transfer heat away from the die. The heat transfer chimney is formed from a thermally conductive compound including thermally conductive nanoparticles.
