A crucible for heating material to be deposited on a target substrate includes a body configured to contain source material, a base formed at a first end of the body, and an emitting orifice formed at a second end of the body. The crucible further includes at least one intermediate orifice arranged and configured such that the heated source material passes through the intermediate orifice and impacts at least once upon the inner surface of the crucible body before passing through the emitting orifice.
