An electronic device is provided. The electronic device includes a communication circuit, a memory, and a processor operatively connected to the communication circuit and the memory, wherein the processor may be configured to detect an event for transmission of a synchronization signal in a device-to-device (D2D) mode, start a first timer stored in the memory, transmit a synchronization signal at a specified first timing during a first time period during which the first timer operates, and attempt to receive a synchronization signal at a specified second timing during the first time period, sense that a synchronization signal and a valid data packet have not been received by the time that the first timer expires, and attempt to receive a synchronization signal at a timing corresponding to the designated first timing during the second time period after the first timer has expired.

Electronic device for synchronization in D2D communication environment and method therefor

A method of forming a material film includes providing a non-photosensitive mask on a substrate to expose a partial region of the substrate, forming a material film on the partial region of the substrate using a sputtering process, removing the non-photosensitive mask, and heat-treating the substrate and the material film from which the non-photosensitive mask is removed under a first gas atmosphere. The material film includes a transition metal and a chalcogen element. The sputtering process may include an RF magnetron sputtering process. The heat treatment may be performed at a higher temperature than a temperature of the forming the material film.
