 Hasil pemeriksaan deteksi dini kanker payudara di Indonesia Tahun 2017 telah ditemukan 12.023tumor payudara, dan 3.079 curiga payudara. Di antara 5 yang paling sering dijumpai,kanker tercatat mencapai 2,09 juta kasus. Untuk mencari faktor risiko tumor ganaspayudara seperti usia, riwayat melahirkan, menyusui, keluarga, menopause,dan pemakaian alat kontrasepsi hormonal. Metode surve...

Highly mismatched alloys such as GaNAs demonstrate exotic electronic properties the splitting of conduction bands (CB) into E－ and E＋ sub-bands, make them promising for novel application. However, incorporation nitrogen atoms in host GaAs severely degrades electro-optical this alloy with added challenges precise control compositions. Here we focus on effect Sb doping compositional thin films gr...

In this letter, we show that the oscillation features sOFsd usually observed in photoreflectance sPRd spectra of GaAs-based structures grown on the n-type GaAs substrate below the GaAs fundamental gap could be eliminated completely by applying the contactless electroreflectance sCERd instead of PR. This finding confirms that the origin of OFs is the modulation of the refractive index in the sam...
